Utah: I will write for the Scott records. I am not sure whether Gallyon's has them (Webley & Scotts) or H&H. Will try to track down. The letters from Scott's that David gave me look definitive, if short.

Bushveld: Jack did mention these guns to me earlier. He will be a good contact, and I think he may know of the man who built of O/U SLE.

Thanks to all for passing tips on.
