I picked this lens up for $50 at a Photorama Show from my favorite dealer. He knows exactly how rare it is, under 2000 made. This one was missing the infinity lock button, needed a CLA. I hade aspare release button from a parts 50/1.5, cleaned the helical, cleaned the front and rear surfaces, did not open it up.
This lens is a classic 1-2-2-1 double Gauss, very similar to the Leica Summar but the glass elements are wider diameter- closer to the Summitar. This is done to reduce vignetting. The lens uses 40mm filters, and is in a single-helical, collapsible mount. It is well made, and looks good for being almost 70. The surfaces are hard coated, some cleaning marks on this one- but nothing bad.

to my eye- much less flare than the Summar.
