This download provides one single-master STL modeled and scaled at 1:87 (HO) representing a WWI-era Model T–style gun truck. The truck reads immediately as an early-1910s light military vehicle thanks to its rounded upright radiator, open two-seat cab, simplified spoked-wheel forms and short flatbed with a circular gun-mount ring. It was designed for model-railroad layouts and small diorama vignettes where readable silhouette and durability matter more than ultra-fine fastenings. Included: one 1:87 master STL (single-piece). Print notes: expect supports under wheel arches, the chassis and the flatbed underside. For filament printing orient with wheels down; for resin printing evaluate support placement for the gun ring and wheel fillets. If you need finer spokes or interior cab detail, scale the master up and add details before slicing. This master is intended to be resized by users for other scales; typical multipliers from the 1:87 master: 1:72 ≈ 1.21×, 1:76 ≈ 1.14×, 1:48 ≈ 1.81×. Use: HO model railways, WWI dioramas, historical wargame props and small display models. Note: this mesh is a hobbyist interpretation intended for visual recognition rather than a precise archival reproduction.
