The scabbard is made of elaborately tooled leather. Materials include coloured, tooled and stamped leather and lacquer over paint. It is bound in wooden cover boards, covered with tooled red leather. They were lavishly produced, with full illustrations, and gold tooled, leather covers. In later years, Russia leather was tooled to give a decorative surface texture. The walls are brick, laid in English bond with tooled joints, over a stone foundation. Colt's tooled up and produced the 15,000 units between April 1921 and March 1922. Both of these engines had been tooled to 1/60th. This can be determined by tooled placement in sample.
