Yes thanks I have contacted this chap. You are correct the tubes he has are too big. He did have one tube that was 25.4 but randomly only had a single crimp on one side!
So I tracked down a builder that had a few sets. However, as you can imagine he was saving them for building up a frame ... and understandably didn't want to part with just a top tube leaving the set incomplete!
