To my surprise, I won a bid on a pair of pre-owned Carl Zeiss 7x50 BG T* marine binoculars. 1/5 of new price. Just under my maximum bid, time ran out for the competition!
Chipped paint. Field lenses look excellent, but the eye lenses have fine scratches, probably from being wiped too harshly. Waiting to test them next time any stars show.
Eye relief with the cups rolled down is OK wearing glasses. I will look for an eyeguard online and buy a case for them. Would Zeiss sell replacement eye lenses if I wanted some?
Congratulations! that is a very nice binocular!!
Regarding the objective lenses, as a reference, sometime ago I replaced 2 objective lenses in a Zeiss 10x50 Jenoptem. each lens was priced at 39 €, but they were Zeiss Jena, not Zeiss West. I would suggest to contact some german optical workshops to ask if they have these Zeiss West spare lenses.
I suggest Düncker Geräteservice in Rathenow and Optixxx in Arnstadt. I have used both and they are specialists in Zeiss binoculars.
A binocular like the BGAT* deserves to be in the best possible condition
