Mamiya RB67 Rare Universal Sports Finder -Mint in Box- (0117-1)
$131.25 USD$175.00 USD
This is the cool and rare sports finder for the RB. The fun thing about it is that it incorporates a partial frame prism finder so you can see the middle and focus critically. It is in dead mint condition in the box and it appears to be unused. This is a rare find.
