Can I just comment on the wheel choice? I have converted an Oxford Rail Adams, and used the Gibson 18 spoke 5’6″ wheel because:
A It will look the part because over the flange it will be closer to the 5’7″ of the original than a 5’8″ wheel.
B. I think there is a minute reduction only in crankpin throw which eases any problem of rods bashing the underside of the footplate without visual loss or loss of crosshead movement.
Just an idea.
