I recently got a Copying Gauge for fun and to preserve another cool Leica historical gadget. The model is BOOWU-M 16526 H. It has three adaptor/spacers with four screw in legs. The idea was/is for copying fixed area documents or similar. The one I got is in M mount and the spacers bayonet to my M bodies. However the side to accept the lens has a smaller, different bayonet. I expected it to accept a normal M mount 50mm. I am familiar with the visoflexes, that use screw thread lens heads without their focusing section and mount. Is this a similar idea? If so, which older 50mm lenses have this removable lens head with a small bayonet on it? Or do they have a thread like the Visoflex lens I have? My references mention an UOORF bayonet adaptor. This looks to be small bayonet to the spacer and screw thread to the lens head. But the instruction leaflet says that some 50mm lenses bayonet directly to the spacers??? You Leica goodies experts, (Marc, I'm thinking of you!) what am I missing here, literally or figuratively??? Cheers, Geoff http://gallery.leica-users.org/v/gh/a/
