Dang it $10K!, Dave that guys Grandpa must a been Mosby or Jessie James ya thinks?
Ya wanna keep the Custer right ... or did the guy with the 1862 Pocket Police say he wanted it unfired/unturned? If so he's a maybe a collector for High $ probly and wasn't gona shoot it...to me it wouldn't matter unless I was buying or trading for a profit.
These originals are cool but hell 100-150 years old or so ... and a bit loose, or will be and some you wouldn't shoot as much as say yur Custer maybe, but I know the feeling of wanting what ya want. I been the same way with my Fredric Remington "Rattlesnake" NMA Always wanted one got it can't bring myself to shoot this one for the same reason as above. It's Purdy collectable and worth more unfired...and dang I got so many Rems I don't need to shoot it ...have but only one 1861 Colt now a 5.5" Pietta/Kirst gated .38spl .
Ask the guy Dave you'll never know if ya don't ask I guess... I had a nice 1861 I got with 3 differant barrels, white or wood grips with grip frame , and two kinds of cylinders sold it for money needed and have kicked myself forever more.
Yours Dave I liked so much for both it being an 1861 Navy and being a 3rd Gen Sig Colt engraved Custer ... it's still a Colt I care not what the Nay Sayers say heh heh
Anyway I'm ujst rattlin' on so ... in the end it's all up to what ya want when they go they are gone and that's how one has to look at it ...
