Robin,
I'm not trying to bash your rifle, but if you think you've got a $1,000 gun you don't.
Assuming it's a .30-30, if it is in excellent condition, and with no box or papers, you are looking at around $400 to $450. Remember, its USED not new. Nobody is going to take your word for it that it is unfired.
With box and papers, you may get $50 more.
If it is a .35 Remington, the you can add about $100 extra to it.
Hope this helps.
If you doubt me, then go to a large gun show and walk around with it. You will see.
