I have a frame that I'm trying to ID. I'm pretty sure it's French & that's about as far as I've got. Someone stuck some Colango decals on it, it's obviously not a Colango.
It has simplex dropouts and a French 531 decal on the forks, I read in my research that a lot of French builders used Simplex dropouts, so that's what my guess is based.
I was wondering if any of you guys had any idea what it could be.
The frame number stamped under the BB is D0036430 (or just 0036430 with a little stamp that looks like a 'D' before the frame no?).
Here's a bunch of pics of the detail: http://www.23hq.com/wblenkin/album/5820489
I would be almost certain that it is a Peugeot of 1980 vintage - see this pic of the bottom bracket on my 1980 PKN10. I think you will see that the 'D' is actually a 'B' - meaning 1980s, and the following numbers are very similar to mine. The main difference is that the numbers on mine must have been stamped after Pierre had a fine glasses of vin rouge as they are pretty wonky.
Here's a rubbish pic of the whole frame:
