Old B&L Bausch & Lomb 8 1/4"  F/4.5 Copy Lens: Macro Lens, Medium Format, etc?

Description

Here's a B&L copy lens that might be able to be used for a few other projects with a little ingenuity! It will stop down to a marked F/8, but will still go beyond that to probably F11 or so.
Cosmetically it shows some light wear.  The glass is very nice; not quite perfect, but should work just fine. The barrel shows some cosmetic wear.  Smooth F-stops end to end.
Thanks to ebay/PayPal's current policies regarding returns, we will no longer sell most items as working, but rather "officially" as parts, not working. Also, thanks to the same policies, we will no longer ship directly to any country other than the US. Any overseas buyers must buy thru the ebay shipping program, or other US buyer where we ship only to a US address.
