has any ever heard of an old .35 Rem that has 2 barrels
my grandpa has one that has an inside barrel that slides back and fourth so the gun recoils multiple times

how much would this gun be worth

Sounds like you are talking about a Remington model 8 .
I know the model 8 could be had in 35 Rem.
Renington started making the Model 8 in 1906 I think.
I have not seen 1 for several years but I know of a guy that still deer hunts with a Model 8 in 30 Rem.

I do not know how much it is worth .
Check the aucition sites for a price.

My father hunted with an old Rem. semi auto in 35 Rem. for many many years, before moveing up to a Rem. 742 in 30-06.

I bet you he shot more than 50 deer with that 35 Rem.!!!
