Gloucester Bogies 5'6" with long couplers

On a fellow modeller's request, these are the same as my other Gloucester 5'6" wheelbase N-gauge/2mmFS bogies but with 7mm longer couplings, to try them under the N-gauge society 'Salmon' engineers wagon kit. By substituting them for the plateback bogies supplied with the kit, it is hoped to model the air-braked conversion of these wagons. The Gloucester bogie shape is roughly right for the ASF bogies actually fitted, and the holes in the frames can perhaps be brought closer to the mark with careful use of needle files. Let me know if you are interested, but would prefer me to improve the side frames before you spend your money.
