"I'll never ever sell a gun," right?.....Sound familiar? Well my wife bought me a Thompson Center Hawken Flintlock rifle for Christmas last year as a big surprise, which it was! BUT now I don't think I'll ever even shoot the darn thing and may put it up for sale. (SHE DOESN'T MIND) Any suggestions on what I should expect to get out of this new/unfired rifle? I think is was bought for a little over $400

Thanks!
