Welcome to the colletors choice!
The choice for Caterpillar and Diecast Masters!
The choice for DCP!
1:50 scale is the professional standard for construction equipment diecast, and it's by far our largest and best-selling scale — the size manufacturers like Caterpillar and Komatsu use for their own official promotional models, which is why serious equipment collectors gravitate toward it. At this scale, models are large enough to show genuine mechanical detail — articulating buckets, opening engine covers, accurate hydraulic cylinders — while still being practical to display in meaningful numbers on a shelf or in a cabinet. Our 1:50 collection spans the full range of what we carry: Cat dozers, excavators, and wheel loaders, Komatsu equipment, First Gear trucks and trailers, and Diecast Masters cranes and compactors. If you're building a serious, cohesive construction or trucking fleet display, 1:50 is the scale most collectors standardize on, since it's the scale carried most consistently across manufacturers and equipment types. Browse the full 1:50 selection below, filterable by brand and equipment type. As an authorized dealer, every model here is guaranteed authentic and new.
