Railway Breakdown Crane
This model is based on the same prototype as that used for my entry in the the “Pocket Meccano x N” Secretary’s Challenge, i.e. a mixture of a Ransomes and Rapier 10-ton accident crane, built between 1880–90 (from a picture) and a Great Eastern Railway 10-ton crane of around 1914 (from a line drawing). Both illustrations came from Railway Steam Cranes by John S. Brownlie (1973).
This time there’s not the restricted list of parts, but it’s built to the same scale of 1:48 or ¼":1’. The frame is now a little longer at 5½” long and wider at 2” to be slightly more to scale.
