Md, I would'nt ask any Gun Show vendors!
I have a Shiloh original 45-90 and was offered $1000 from a vendor and it's worth over $3000.
Also have an Original Springfield 1863 .58cal, worth about the same.
Them guys know what you have and how much it's worth. They see $$$$ signs on some pieces.
They gamble that you are desperate to sell.
