It's a standard 111 (F) where "F" stands for "förnicklad" = nickel plated. You will find a couple in the 111 section of the stove reference gallery Optimus No:111 (all variants) + later Hiker & Hike
Ok, I've never seen a 111 with a nickel-plated tank before. Thanks. I bought it yesterday. Saw it online and threw in a bid. Can't wait for it to arrive in the mail.
Hi. Twodogs excellent post: Putting a date to Optimus 111 Reports that Op.111 stoves produced in the 1950s were supplied with Cookie-cutter spindle key available in Black, White, Red, or Green. There does not seem to have been any obvious pattern as to which colour of regulator knob was fitted on a particular Op.111 stove. Best Regards, Kerophile.
Recived this today. Great condition. Just in need of a service and some cleaning. I have all the parts.
