These pictures are from items in my personal archive. I do not like sharing it on the internet.. Pictured below is the oversize postwar artwork for the logo. (with adjustments using white out) squaring arm off straight instead of a radius etc. Than etcher reduced artwork using photography to correct size to make etching plate template.
2nd photo is of the postwar etching plate. Still with black wax resist on it.. Also of the 4 logos on the plate notice the top left logo, Radius at end of arm.. Regards:
