1/35 US PT-556 Elco "Thunderbolt" 20mm Quadruple Gun Mount

1/35 US PT-556 Elco "Thunderbolt" 20mm Quadruple Gun Mount: Patrol Torpedo Maximum Firepower Fidelity

Bring an exceptional layer of technical density, aggressive mechanical authority, and naval combat realism to the aft deck of your large-format patrol boat models with the masterfully engineered 1/35 Scale US PT-556 Elco "Thunderbolt" 20mm Quadruple Gun Mount. Officially developed as a heavy-hitting, field-tested anti-aircraft and surface-strafing upgrade for the United States Navy's motor torpedo boats, the formidable "Thunderbolt" mount clustered four 20mm Oerlikon Mark 4 rapid-fire autocannons into a single power-driven, joystick-controlled turret platform. Famously mounted aboard the 80-foot Elco boat PT-556 operating with Ron 29 in the Mediterranean Theater, this devastating battery turned fast patrol craft into lethal gunboats capable of shredding enemy coastal convoys, armed F-lighters, and low-flying Axis aircraft. Scaled precisely to the popular 1/35 military modeling scale, this dedicated standalone ordnance centerpiece faithfully reproduces the armored gunner enclosure, quadruple Oerlikon receiver housings, turned-profile slotted cooling barrels, drum magazine brackets, hydraulic/electric traverse drive motors, and heavy circular deck turntable ring of original Elco and Bureau of Ordnance (BuOrd) engineering drawings with flawless fidelity.

Engineering Precision and Motor Torpedo Boat Armament Fidelity

At 1/35 scale, heavy automatic ordnance commands the entire aft profile of a patrol boat, exposing barrel concentricity, gunner sighting links, drum magazine details, and hydraulic drive tubing to intense visual scrutiny. This replica quadruple mount captures the aggressive, compact industrial silhouette of frontline American small-craft weaponry with surgical clarity, eliminating the thick, soft-molded plastic contours, flash distortion, solid-cast sight assemblies, and barrel droop typical of mass-production plastic kits or heavy white-metal conversions. Deployed onto the aft engine room hatch deck of your 1/35 scale build or showcased as a museum-grade standalone naval ordnance exhibit, each component features true-to-scale physical relief, creating realistic physical shadow lines and deep mechanical contrast that standard kit placeholders cannot match.

• Museum-Quality Arsenal Replication: Developed using original technical layouts, historical U.S. Navy Bureau of Ordnance blueprints, and archival Mediterranean patrol photography to accurately reproduce the exact physical dimensions, quad barrel spacing, gunner shield enclosure, and circular base turntable geometry of the operational "Thunderbolt" mount as fitted to PT-556.
• Prototypical 1/35 Patrol Craft Scope: Specifically engineered for large-format 1/35 scale PT boat subjects (including Italeri 80-foot Elco PT boat kits), custom scratch-built hulls, riverine conversions, and museum-grade naval diorama displays.
• Exposed Hardware & Mechanical Detail: Authentically captures the four 20mm Oerlikon cannons with slotted cooling jackets and flared conical flash suppressors, top-mounted circular drum magazine clips, central gunner bucket seat with control grips, forward armored splinter shield with optical sighting notch, internal hydraulic elevation pistons, traverse gear rings, and circular deck mounting flange with raised structural fastener bolt impressions.
• True-to-Scale Volumetric Depth: Replicates the true physical three-dimensional presence of heavy naval gun steel and structural aluminum, casting realistic deep shadows beneath the overhanging quad barrels, inside the open gunner cockpit, and around the heavy deck turntable base.
• Streamlined Deck Integration: Engineered with a precision-molded flat base contact ring designed to seat cleanly, squarely, and securely flush onto standard 1/35 scale Elco deck surfaces or raised armored foundations, drastically reducing assembly friction and streamlining installation.
• Intelligent Material Optimization: Expertly designed in High Detail Resin Grey with an optimized structural profile to manage material mass while preserving maximum rigidity, ensuring crisp, warp-free barrels with dead-straight concentricity that resist drooping, bending, or distortion over time across all four guns.

Premium Material: High Detail Resin Grey

To satisfy the absolute highest demands of micro-detailed static presentation across delicate scale ordnance and specialized naval weapon mountings, this "Thunderbolt" quadruple gun mount is crafted exclusively from premium High Detail Resin Grey.

• Exceptional Feature Definition: This premier formula achieves surgical multi-dimensional precision and an ultra-smooth, non-porous surface finish, capturing the finest mechanical facets—from razor-sharp barrel cooling slots and flash suppressor vents to miniature control grips, magazine latches, and turntable bolt heads—with absolute sharpness and zero layer line distraction.
• Professional Foundation: Provides an ultra-smooth base specifically optimized for high-quality marine primers, fine-scale technical pin-washes, micro-masking, and authentic wartime US Navy camouflage finishes, ensuring flawless paint adherence.
• Superior Quality: Manufactured by distefan 3d print, ensuring clean surfaces, parallel barrel alignment across all four weapons, and outstanding dimensional integrity for a luxurious, professional-grade finish.

Key Features and Specifications

• Accurate 1/35 Scale Precision: Precision-engineered for seamless, historically proportional integration with standard 1/35 scale Elco PT boat models, scratch-built hulls, and coastal diorama displays.
• Historically Authentic Fleet Hardware: Faithfully represents the physical configuration of the specialized quadruple 20mm "Thunderbolt" mount deployed aboard the USS PT-556 during combat operations in the Mediterranean Theater.
• Complete High-Firepower Weapon Station: Delivers the full multi-barrel weapon system, gunner shield, drive motors, and mounting pedestal as a unified, high-integrity master assembly.
• Hollowed Lightweight Rigidity: Features an engineered structural geometry that minimizes top-deck weight on the mahogany hull while maintaining exceptional structural stiffness across slender barrels and control linkages.
• Unpainted Finish: Arrives completely unpainted, providing an open canvas for custom finishing. Customize the assembly to reflect Mediterranean Theater camouflage patterns (such as green/gray disruptive schemes), overall Dull Black, standard USN 5-O Ocean Gray, or weathered frontline patrol finishes.
• The Definitive PT Boat Battery Overhaul: Replaces simplified, soft-edged plastic parts with a sophisticated, mechanically correct three-dimensional representation of the ultimate close-range patrol boat weapon.

A Canvas for Battle-Tested Fleet Artistry

Arriving in its raw finish, the 1/35 US PT-556 Elco "Thunderbolt" 20mm Quadruple Gun Mount serves as the ultimate starting point for advanced multi-layer painting, precise component color-blocking, and realistic maritime weathering.

• The Mediterranean Gunboat Scheme: Base-coat the armored shield, mounting pedestal, and turntable base in authentic period-correct camouflage colors—such as USN Ocean Gray (5-O), Mediterranean field-applied olive green, or disruptive dark tones matching your PT-556 reference photos. Paint the four 20mm Oerlikon receiver bodies, barrels, and flash suppressors in dark gunmetal, burnished steel, or oily graphite, picking out sliding breech areas in polished bare metal. Finish the 60-round drum magazines in dark Parkerized slate gray with subtle brass primer details on exposed ammunition rims. Detail the gunner seat, control joysticks, and sighting links in satin black and darkened bronze to create striking functional contrast.
• Realistic Frontline Operational Weathering: High-speed patrol boat deck weapons thrive on rich washes, textural filters, and environmental staining. Apply rich dark raw umber and soot black oil washes into the barrel cooling slots, around the drum magazine brackets, and along the circular deck turntable ring to establish deep structural shadows. Add realistic weathering effects like bare-metal chipping and silver scuffs along the gunner shield rim and footrest where the operator braced during high-speed combat maneuvers, intense powder soot trailing back from the four muzzle flash suppressors, dried white salt spray mineral crusting layered across forward windward surfaces from charging through Mediterranean chop, and vertical rust or water stain streaks weeping downward from the baseplate bolts across the aft mahogany deck to capture the true look of a veteran gunboat ready for night action.
