1932 Elmar 50mm 3.5 - no grip on front ring
Bought a 1932 black Leica ii(converted to Leica iii at some point). It has a 1932 Elmar 50mm f3.5 collapsible lens on it. I notice the outer front ring of the lens doesn't have the grip like every other Elmar I have seen. Can that grip be removed? How is attached. Glue, bonded, soldered? Can this be how the lens was made or could it have been machined or ground off.
Any advice appreciated. Photo attached.
