Does anyone have photocopies of the description for the Midland single wheeler.

When was it described, I believe it was the arly 1970’s. Any information would be helpful. I am also in the hunt for a second hand set of drawings.

I would also value any old castings for this you may have.

You want volumes 136, 137 and 138 for “Princess of Wales” by Martin Evans.

I am still interested in any spare castings you may wish to sell. Unmachined or machined I am interested and will pay.

Try putting a wanted ad in the classifieds; it will stay visible for 3 months rather than in a thread which soon drops out of sight

A fresh question.

On another board I asked about using BMS with Iron liners, instead of an expensive gunmetal casting set from Reeves

The problem with that is that Martin EVans design calls for slide valves. I now know that the orginal Midland engine had piston valves, which would make an easier job using round liners for all 4 bores in the block. This getting way beyond my compentancy. I can machine it, but the redesign is not my field. Has anyone produced a set of pistons/valves/ block for this engine, especially drawings. have you done this and have sketches I can follow. Any help would much appreciated.

Thanks
