I would look for guns similar to but not limited to: http://www.gunbroker.com/Auction/ViewItem.aspx?Item=190013442.

Or this Ithaca at:

Ask the seller all pertinent questions, such as rust issues, bad dents, possible looseness with ribs and lock-up, chokes etc...

I bought a 1896 Remington 1894 damascus ejector gun for $1150 mid summer in so good a shape, all it needs is a hunting schedule.

Good luck!
