I remember those ads also, Larry. Thing is, there was no internet, and you couldn't see the guns he was talking about.
Things have changed.
I don't have a "collection". I have an "accumulation" and a few of those are like my 16 gauge Nitro Special-a gun that was truly unused, with stock and action in 99+ % condition, and the barrels covered with furry rust on the outside. Bought cheap, reblued, and not a lot of money outlayed. If a dealer comes up with one like that, he will want most of 1K for it, and it is buyer beware. Warms my little heart knowing what it was before the barrels were reblued.
I'd rather be the guy who finds it before the dealer.

Best,
Ted
