Side-Lever Martini

[albayo]

I have a friend that says he has a Side-Lever Martini, and is thinking of parting with it.
It is a full wood model and he would like to get a ball park figure of it's value? Are they rare?

Thanks

Boy...some pics would be helpful. There are a lot of variables. Condition... condition...condition. Caliber?
