Hi all, I recently purchased a 70s tt frame, something I've always wanted... think Alf Engers style. On arrival I noticed what looked like a crack around the seat lug where the stays connect. I took it to a local frame builder who couldn't tell whether it was the paint or the steel itself. When I took it home I took a tiny bit of paint off to check and it unfortunately has a crack. As I purchased it off Ebay I can send it back for a full refund (seller has agreed).. however my issue is that I really like the frame. As mentioned I've wanted a 70s tt frame. It's very light, 2.15kg with forks. I think I know the answer which is just return it and keep on the lookout for another. However how repairable is something like this and roughly how much would I be looking at? Is it actually possible, for context the downtube and seat tube are the same external diameter at 29.3mm (seat tube id 27.2mm) the top tube is just under 26mm measured painted, so maybe the lug has been modified to fit
