I bought one of the Lomond ex-hire jacket and waistcoats on ebay. The buttons feel a bit cheap and there are no inside pockets on the waistcoat or jacket. The condition of both jacket and waistcoat was very good. As for UK vs US sizes I don't know but the jacket was a 42R and I'm a 41 inch chest and 42R jackets tend to be a bit long on the arm on me. The vest and jacket fit me surprisingly well. All in all I'm very happy with the purchase.

On another thread I wrote about how I didn't like the modern kilt jackets then like a true hypocrite I promptly went out and made my ebay purchase!
