Cal Scale 190-3006 – O Scale Steam Locomotive Whistle
Cal Scale 190-3006 is an O Scale steam locomotive whistle, cast in lost-wax brass for adding fine mechanical detail to steam locomotive models. It is suitable for super-detailing locomotives, kitbashes, and scratchbuilt projects where a separate whistle casting is needed. Bowser lists #190-3006 specifically as a “Whistle” in its O Scale Cal Scale range.
