I...the scope mount and bolt and safety work look to be G&H..... I too wondered if there were any marks on the barrel that they didn't mention.
I'm largely ignorant (or unobservant) of what box-stock USGI M1922 safeties should look like. What particular things did G&H do to the safety mechanisms on these, please?
And mine has no visible Griffin & Howe markings on the barrel, but I vaguely remember reading that they might have stamped their work-order number or something similar on the underside, where it's concealed by the wood. Haven't had its action out of the stock to check, and the previous owner never did, either.
