If the down tube is Reynolds 531DB, there should be a 2nd line, under the first, stating "D/BUTTED XX/YY", where xx/yy is the tubing gauge. What is the outer diameter of the seat tube? Also check, with the seat post installed, if the cinch slot is noticeably narrower at the top than the bottom.

Well, the outer diameter of the seat tube is 28 mm. And, the cinch slot is noticeably narrower at the top than the bottom. BUT! I can not insert any seatpost except this one, marked as 25.4. So, i check the inner diameter of the settube - close to 26.4. So, it can be French standard seat tube.

I can not find any stamps except REYNOLDS 531 (

And i know that some Raleigh Record Ace have 531 tubes and 25.4 mm seatpost.
