W-KOMURA 24MM F3.5 MFG.LTD NO.8437113 VINTAGE / ARGENTIC LEN À LYON

I sell my extremely rare W-Komura 24mm F3.5 MFG.LTD because I need money, really good aspect, fantastic bokeh, and have the particularity to be Thorium-treated, so, it's a radioactive lens (donc worry, if you carry it 1 month 6h/day, you'll only have 1/1000 of a thorax radio, so really nothing) but the light is quite yellow, like a really old photography, it's an amazing lens for b&w pics ! This lens date from 1953 to 1962, I don't have the exact date. Komura brand is also knewn as Sankyo Kohki. In 2 years of research, I never found an other one! I only found a 35mm F4 Witch had the same style, it was from 1954 and was selled at 230€
