Go over to Propsummit and there is a thread called "Tomenosuke cylinder engraving" .
I recently made a cylinder for my Tomenosuke and asked the members there if the
"A" engraved on the cylinder was stamped on the actual prop.
A few members there want cylinders to so I offered to make them.
I own two, and they ain't cheap either as we know. But I have to say I am "Tomen'd out" with all these versions that have
subtle differences.. I'd like to see a new company offer a competing product not restricted by Japanese laws and have all the precision of computer designed parts.
