I've just bought this Harry Hall as a renovation project to get ready for the spring/summer. I know the man I bought it from, a keen cyclist in his 70s, and he says he bought it in the mid 70s second-hand, so it could be 60s. It has been hanging up in his garage for years and he now just rides his two Mercians, so when I mentioned I was looking for a project in my size he said I could have this for £25.

It has virtually indecipherable 531 stickers, campagnolo dropouts and the frame number under the BB says SK44JJW55. Pretty tatty and I haven't been able to ride it yet but the frame is sound and it has the weight and feel of a decent bike so well worth the money.

I haven't decided on a colour scheme yet, nor how much I am going to keep it period correct as far as the components go.
