Agree with what u say and what shop do or so call collector do. But we all use collector loosely. The collector I know of buys the Noctilux new 3 copies as an example. They seldom go to second hand store to buy. If they sell, they sell to fellow collectors, people with room full of cabinet and mint unused set of Contax, Leica etc. If they ever go out of their house to look at a 2nd hand lens from B&S, they do not carry torch or look for scratches haha. I met one collector, one look and he tells me my rigid cron, which is mint by any standard, has a slight discrepency in the colour between the top lens portion and the bottom portion and he suspect somebody might have swap the parts to make that lens mint. We had a really good chat, no mention of money or lens after that and certainly do not even need flashlight haha. Just sharing cheers
