FK 13x18

Happened to see one for sale at a local flea market. Unfortunately photography is not allowed there, so I can only tell with words that it was marked FK 13x18 NO01990 1947g and with I-51 21cm lens serial 479433. It had half a dozen film backs, and looked very good, unrestored original. Price was a hefty 350 euros though, so not something that would have interested me.

Best regards,

These FK's are priced all over the map.. sometimes I see them as low as $100, sometimes close to $1000.. Was it Leningrad made? Shutter or no?

L'grad made by the logo, about the shutter I honestly can't tell w/o closer inspection. In my opinion looked like it should: not recently rebuild = too modern, but aged yet still not worn out. I could ask for permission to shoot if needed?
PS: Your parcel is soon on its way, thanks!
