Questions or thoughts for the OP:
This situation sounds at least odd... or uncommon. You've got some collector grade guns here in these photos and you say a friend is looking to sell part of his collection, but you don't even know what you've shown us. Does your
friend know what he's offering you?
(could be that he received this in an estate and doesn't know or care much about revolvers, and is not interested in them... totally plausible, perhaps that's what we've got here)
However, if he is a gun guy and a collector himself, it seems as though he should certainly know what he's got here in most of these. And you really don't seem to know... It's curious that you are an interested buyer. Most folks (who don't know much about these) that find an opportunity to buy a handful of collector grade guns typically find themselves in such a position because someone
else selling them also doesn't know much about them.
Let me put this another way...
If the
seller knows what he's got... and the buyer does not...
It looks like a setup for radical failure. As in... that collector grade Diamondback is a sweetheart and a fantastic investment if you get it for a thousand bucks, but if the SELLER knows what it is and the BUYER doesn't and the BUYER pays $2,500 for it and has
no earthly idea how to inspect it for function, originality, condition and value. the BUYER might well be taking in right in hindquarters.
The single picture we here are all looking at make it appear to be fantastic, and it may very well be, but the possibility exists that it could have some issues that will attack the value. Afterall, we only see the single image. It's almost no matter if you pay a thousand bucks for it, because it -IS- that sought after. However, if you are asked to pay a current market "price" in 100% condition for it, when THAT gun is currently sitting at it's all-time high right now, then:
a) it sure as heck BETTER be at 100%, which you aren't qualified to deduce
b) it's much like buying gold when gold is at an all-time high
...in other words, it "might" be a good investment, if gold continues to climb, but it's throwing money down the toilet if gold happens to be inflated and it comes down from it's peak. You end up with a revolver you spent $2,500 on that you might never be able to sell for over $2,000.
As a side bar, it appears that everything (except the top-break) is sitting in it's original box. Many (most?) of these boxes have information on the end panel of the box that will help you (and us) identify them. You didn't notice that? Or the seller didn't?
This is obviously an opportunity for some very nice examples here, but it sounds like an odd or uncommon scenario. I'd like to hear more with regards to how this came about. Whoever owns these guns... may very well have quite a valuable lot right here, so naturally, it raises an eyebrow that he's offering all of them in one fell swoop to someone who doesn't seem to know
anything about them.
I believe in the good in people, but realize that it simply is not always the case. If the Diamondback (just one hypothetical example) has the original owner's SSN etched in to the steel of the grip frame where we cannot see it (on the reverse side or under the wood stocks) then forget whatever you think you know about it's "value" or what it would sell for, because it would be in it's own unique place in the market. (it would be miles below "mint")
