Yashica Lynx-1000

aka Yashica 35 Lynx

This one is from August 1960

Fast f/1.8 Yashinon lens with Copal shutter up to 1/1000 sec

This one may have had a lens made by someone other than Tomioka Optical. It's a stretch but, it may have been made by Zunow Optical (or maybe not) - that comes from unsupported statements on some Japanese blogs.
