I have a friend that builds customs, Jack Huntington. I recommended him to someone, and, that person had a gun built. The problem was the person ordering the gun had only bought guns that were already finished, and, his expectations of what was included, and what wasn't, were two different things. UPS gets rich on such deals, and, even though handled well, it cuts into the gunsmiths' profits. The buyer needs to know the right questions, and, the seller has to ask them. Both parties usually are at fault in these kinds of miscommunications.
My first custom was like that. For nearly 1k in 1980, I thought blueing the barrel and cylinder would be included by John Linebaugh. I was wrong...
