I know what you mean (and why you want it), but does it hold value to your though? You want something specific and what’s offered is nothing like that. The chambering is wrong, which is kind of a big deal, if you want to see what was actually shot. You are settling and giving up. I am telling you that there are heaps around, you just need to look proactively (e.g. call around, place an ad).
Re: someone placing an ad… Yeah, “looking for asian guns” - I’ve seen that one. And a shitty picture, doubt it’s going to get a lot of responses. Who knows, maybe. When you sound like a collector, people want to sell you things at collector prices. By the way, speaking of, that arms auction, add a few hundred dollars and then 18% on top (auction fees and taxes), that will be the actual price.
Whenever I placed a “wanted” ad, I was specific, I included a good photo and I got responses. One thing I did notice is that there were a few people who wanted to call and talk about their awesome collection and how someone told them once that this was the rarest of the rare guns and you will never find one like that and please let me keep talking for an hour and tell you what shade my socks were the day I found this gun for $30 in 1953. True story (minus the socks), happened a couple of times. I stopped listing my phone number. The moment I did that, just contact via website (up to a week in my experience) were all legit sellers and I always found what I was looking for.
