I have these M1908 binoculars by Rodenstock. They have a black coat of paint over the original field grey. The case is also black with straps that have what looks like GFF 43 on each one. There is also a marking on the edge of the lens which looks like JR, but may possibly be IR?
Can anyone tell me if the black paint may be an issued re-paint and if the GFF 43 means anything? Also, any ideas on if the JR is initials?
Thanks in advance!
