Identifying a vintage Swiss/French frame

Just started a winter ss bike build and picked up a NOS french frame that looks like 70s/80s. The paint wasn't finished as it doesn't appear to have a top coat, so no decals.

Anyway, no idea who made it so wondering if anyone can help. Here's what I know:
1. BB thread is 35x1 so I guess that makes the frame French
2. 126mm spacing
3. Serial number is on a plate on the back of the seat tube with the no. +26512
4. Some pics of the lugs and dropouts that might help
Cheers!

Actually just realised that the plus at the beginning of the serial number is probably as Swiss cross. So it might be Swiss...

Are drive and non drive side bottom bracket threads in the same direction or different?

Different direction, so I guess Swiss? I had to pick up a threadless BB as I couldn't find a Swiss BB with a short enough spindle for chainline.

Have also had 3 seatposts trying to find the right size... doh.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

Just like Github, a blank line must precede a code block.
