No idea really . must be a late 1800's early 1900's with the Anastigmat engraving.
Funny thing is it seems to have a RR in the engraving. Maybe it's an early misuse of the word Anastigmat and is a f6 RR w/ Jena glass? Like a Euryskop?

Short for lamborghini?
F6 RR. Not the original fitment from Underwood, I would guess.
