3 1/2 inch gauge Clarkson B2 castings

A set of largely unmachined castings for a 3 1/2 inch gauge LNER B2 "Royal Sovereign" by Clarksons of York. Bought in 1973, progress has been slow and steady to date - the builder machined the driving wheels, erected a set of frames complete with horns, axleboxes and pump sheaves and built a copper boiler.

Complete with a set of original Clarkson drawings.
