Mamiya Sekor C 65mm f/4.5 lens for RB67 Inherited from Dad, it works perfectly AFAIK - no fungus, scratching or damage, aperture stops down smoothly and all shutter speeds sound correct. It's dusty and I don’t have caps for it, but the original case is included. $100 US plus shipping from near Washington, DC. Listed this last year, so let's try again fresh.
