Best gun buy

In the mid '80s I was at a gunshow and saw a S&W revolver the Standard Catalog identifies as a " 357 Magnum Model of 1950, Pre-27," made January 1952. It had a 3+7/16" barrel. "S" prefix, five-digit serial number. I don't remember what the seller was asking for it, but it was high, for me, though likely appropriate for one in good condition. It was in very good condition and I remember particularly admiring the checkering. Finish wear suggests it was actually carried for duty.
BUT, when I shined a light in the barrel there appeared to be a chunk missing from one of the lands. I handed it back to the seller with my light and bore viewer. He agreed and asked what I'd pay for it. I said $300 and he said "Yes." I was taking a chance buying like that because I really believed a chunk was missing and I'd have to replace the barrel. I knew a friend had a 4" Model 27 barrel I could have for $50, and that he'd do the change no charge.
BUT, I got it home and pushed a cleaning patch through the barrel and a chunk of crud fell out, leaving a pristine bore. As in "Perfect."
I got a letter from Mr. Jinks in 2002, verifying it is as it was when shipped.
I don't know what it's worth in the marketplace today. I see asking prices from $1,000 to $3,000. I won't sell it.
There are a couple other guns I got at, let us say, opportune moments, but this one takes the "dollar sign" and "good deal" prize.
