200 lpi Ronchi grating from Edmunds optics (1" square)
and an inoperable Pentax K1000 body (the bayonette-style
mount is fine). They were used for knife-edge focusing
(the construction is simple and can be found in the mapug
archives). Selling since I now have a new camera. I would
prefer to sell them both together. $50 and I will pay for
shipping within the US.
