ROKA Prototype Models (HO)

Founded by Bob Stears, ROKA Prototype Models has established itself as a premier boutique manufacturer in the HO scale market by specializing in “never-before-modeled” rolling stock with extreme prototypical accuracy. Since its emergence in the early 2020s, the company has focused on filling niche gaps for North American modelers, debutting with highly detailed Whitehead & Kales “Safe-Pak” auto racks before expanding into specialized GATC tank cars and Evans all-door boxcars. By prioritizing museum-quality detail and rigorous historical research, ROKA has carved out a distinct reputation for producing small-batch, ready-to-run models that cater to the most discerning collectors of the mid-to-late 20th-century diesel era.
