It's important to know whether it has a sliding or a rotating safety. The early sliding ones could slip back and forth betweeen "S" and "F" very easily with casual handling. Very dangerous going either way They corrected this by changing it to a rotating safety.
I got one in a "batch sale" a long time ago. It has its uses. I keep mine in a handy hidy place as a BUBUBUG ("Back Up Back Up Back Up Gun") but I didn't trust the sliding saftey on it, so I disabled the safety and will not keep a round in the chamber. I took it down to the range about a year ago just fer grins and it seems reliable and reasonably accurate for its sights. Let's remember it is not intended to be fired 10,000 rd, like a Kimber or something like that --it's more of a dance-hall-girl's garter gun.
With the box and other stuff (although I hate that "holster" shown, with the open trigger cut-out) it might be worth $300 to someone since it's supposedly unfired. Let's face it, even poor folks and dance-hall-girls have a right to self defense, and the .25s are
really concealable.
I'd think maybe $200 would be a lowball starting point for negotiation, if I were interested in it. If.
$150 if it has a sliding safety.
I had a real estate broker tell me once that "If a house doesn't sell, raise the price --you get a better class of lookie-lous that way." I was never sure if he was kidding or not. But let's also face it, any commodity is worth what someone will pay for it in an arm's length legal deal.
I also suspect the .25ACP is just as powerful as a .22LR in a short barrel like that, but I never confirmed that and don't really want to.
It at least allows one to say, "I have a gun,
get back!"
What happens after that is anyone's guess.
Oh, almost forgot. Fingerprints wipe off that chrome plating real easy.
