It is difficult to identify the plates because the supply was so inconsistent. When Maughan could not supply rear plates and could not give a date when new rear plates would be available, I bought the single plate and had it copied. My copies could easily be mistaken for Maughan plates. Slater or Ted Davis could have done the same when making their plates.
I am somewhat amazed that the plates could be improperly machined. When I machined my plates the axle hole seemed to be the only obvious place to start. I was amazed at how simple the machining was. All the holes are equidistant from the center. The heights on both sides are indexed to the facing of the axle hole also. A short session on the mill will finish them off and the holes can be bored properly. I am not sure how you could do the machining without a finished axle hole?
