we had two frames welded together to form a tandem built it up with steel parts it weighed a ton but we still managed to do a 22.58 10 on the old U7 course on the A38 back in 1980……
That looks like a very nice paint job & my only critique would be the 531 fork decals are slight too low…..the black decals go well with the red IMO as the paint really does pop 👍
Looks like a lot of rust near the BB on the chain stays…..that’s a leave it jobby unless you are prepared for an expensive repair at a frame builders……as 753 once rusted is basically a replacement job on that tube! Having in the past talked with “Pongo” on a 753 frameset back in the 80’s…
