Hi Tom.....welcome to TFF.
I hadn't heard of a Geo. Fisher shotgun before, and I find nothing in my refrences about them, but I did find two for auction on the internet.
From the prices listed, it would't appear to be a particularly valuable gun.
On your pre-64 Winchester Model 94......gonna need a lot more
information on this gun......
Serial # (you can X out the last two digits if you wish).
Condition (% of original finish left)?
Plain or fancy stock?
Takedown or solid frame?
Can you post full length pictures of it (both sides)?
