If the 1911 has all the oem parts, and is in good to great condition, it's probably worth a lot more than you'd think.
I Just helped a friend sell an old (like new) military rifle , a Madsen, he'd inherited from a recently departed friend.
The Madsen has an interesting history..google it if curious. I thought it might be worth maybe $500. 'cause it had the oem sling & bayonet.
Posted a pic of it on a local gun forum , asking about info on it & its value, if any info was known.
One guy posted they're selling for around $900., if in good shape & the bayonet alone was worth $100.00+ as they're rarer than the rifle.
About a week after posting my photo of the rifle, another guy posted a ?, wanted to know if the owner wanted to sell it.
.I asked him to give me an offer, & I'd ask they owner if he'd sell it for his offered price.
Rifle was happily purchased for $1100.00 this past weekend.
Surprised me, my friend was happy with the offer, & the buyer was happy with his new rifle.
My point is.. do some research, it may be worth more than my expect, esp. if you can find a collector that wants one, & doesn't already own one.
