Rare is just a selling hype. Some things are only rare because they were crap when new and still crap. Some things are rare because they got used up. Something’s are rare because they just did not sell. I can see a very high grade gun being rare because few were made but calling any run of the mill gun rare is dealer hype. Had one dealer telling me I need to buy his 26” gun because in time those rare short barrels would be what everyone wants. Still waiting on that to happen.
I agree Eightbore. Really rare is rarely rare, just claims to being rare, often when they are not really rare. If it was a catalog item they are not likely rare. If they have been refinished then rare means absolutely nothing to the collector. You are more likely to call a high grade gun rare because they made fewer of them. But if they made a thousand or even five hundred are they rare at all?
