7 1/4 inch gauge "Koppel" 0-4-0 rack locomotive castings & boiler kit

A large quantity of machined and unmachined castings, gears, laser cut frames, part-assembled flanged boiler kit and other parts for a 7 1/4 inch narrow gauge Orenstein & Koppel 0-4-0 rack locomotive Ken Swan's "Koppel" design.

Built by a highly experienced engineer responsible for many locomotives, stationary and internal combustion engines; work to date is to a high standard.

Complete with copies of the construction articles serialised in "Engineering in Miniature" magazine.

If you need to remind yourself what this technically interesting, highly detailed design looks like we sold a superb one last year, listed in the archive here.
