Just replaced these with faster (although not as pretty) rangefinder glass from Mr. Gandy.
The 28mm skopar 3.5 is the silver version, only mark on it is a few small hood blemishes. asking $439 on this beauty.
The 50mm Heliar 3.5 is also the silver version (not nickel) It is the 101 edition.
very rare to find. asking $465 on this rare unique lens.
PM me for photos.
