For sale is a user condition (KEH BARGIN grade) Mamiya N 50mm f4.5 lens with external finder for the Mamiya 7 and Mamiya 7ii. Price is $700 and that includes paypal and USPS Priority Mail (insured).

The lens performs flawlessly and I haven't had any issues with it.
The lens and finder show signs of use on the exterior and there is a tiny hairline mark on the front element of the lens (see last image). The lens and finder are free of fungus and haze. They both have been kept in a non-smoking environment.
Lens comes with finder, b+w MRC 102 ND 0.6 filter, B+W MRC UV, hood, caps, and a neoprene lens hood.
