Found an Eddy Merckx Crescent in a pretty bad shape so I've been removing the paint. The original paint was very similar to the last pic but no chromed chainstay and a different type of brake attachment piece (bridge?) on the rear.

There's a marking on the downtube for "Reynolds 50 tubing". Due to forum restrictions I'll try and get away with putting a link to the photos in disguise: ( ibb.co / album / FgrM8W ) note, it's co, not com.

Thank you for your valuable work!
