Chummy sharter handle guides

[Robert Leigh]

I have had both aluminium and steel guides for the handles among my stock of bits, but I had not previously been aware of the cotter pin type handle in use for a mag engine. Looking on the various parts lists appropriate to mag engines both types of handle are shown in them all, but there seems to be no discrimination between the types of guide. In my sample check the same part no was quoted for the guide in them all. So the riddle of which is appropriate to any date remains.
