That's really useful info Marcus. Good spot on the brake eyes. I'm waiting to hear back from the seller about which the other parts are still in place. Early days yet but we'll see what the price goes to and how much work would be required. I might have a Holdsworth to go and have a look at next week too.

Best wishes, Mike Kelly London UK
