Winchester made the Model 54 in .30/30 caliber. Not a lot of that caliber were sold, but it was made for a rimmed cartridge. I have a Model 54 with a Sedgley barrel marked .25/35. Do I have the only .25/35 bolt action rifle in existence?

The rifle has a bolt with a gas hole in it. The Model 54 does not have a gas hole in the side of the receiver ring. Is this a Model 70 bolt?

I will not attempt to post pictures because I don't know how, and, secondly, it is not a fancy gun.
