Identify an unknown frame from probably around the 80s
 

I recently got this random frame for free and try to identify it for my project.

Some details:

- Bocama lugs (BCM logos on lugs with numbers 67 and 70)
- "B10023" on the bottom of the top tube
- Suntour headset
- Simplex dropouts
- BSA bottom bracket (68mm)
- was originally (splatter) colored with bright red/orange, white and possibly green (some remains were found under the terrible blue/black paint)
- quite long frame (seat tube 51,5 c-c, top tube 57 c-c)
- stem steerer diameter 21mm, seat tube diameter 26.2mm
- rear fork width 126mm, front fork width 99mm (approximations)
- probably used to be a 26" MTB or hybrid due to the brackets for cantilever brakes for 26" wheels
- no other text or numbers found on the frame

See pictures before and after removal of the ugliest paint ever.

Thanks!

unusual to find a 26" Mtn. frame with lugs, certainly rare to find one built with BCM lugs and Simplex DOs. Given that and the splatter paint and serial number, I'd say it's a European-made (maybe French) frame from a major brand and mid-'80s era. First thing I thought was "Peugeot", but looking at their catalogs this doesn't seem to be one. Unicrown fork might be original, but could be a replacement: are the forkends marked?

Wait. You removed the cantilever brake bosses?

I don't get that either, I wonder what the plan for brakes is?

Looks like he is going for a fixed gear since he also cut off the RD dropout, I would guess there is no plan for brakes.

I wonder if the OP's name is Drew.

Same color could be found on the fork, too.

As some of you are asking why I removed the cantilever brake bosses, it's going to be a single speed and no need for them.

Thanks for ideas, not the easiest one to surely identify :)

The frame is in Finland, so your guess about Europe could be right.

Whatever it was, it isn't anymore.

When does a single speed not need brakes?

When it is ridden on a track. Only then.

That would be fixed/track. Hmm. Fixed MTB?

Well, a track bike has only one speed. I was just answering your question. I've seen a few fixed MTBs. All of them had brakes.
