I am selling this for my grandpa i know most about the gun but not all and i am not a gun crazy nut however i have had this gun looked at by 7 different gun smiths/ Shop and from what they have said i know what i have.
This is very very nice pre 1964 model 70 chambered to a 257 whether-by magnum. Originally was a 257 Roberts but was change by a gun smith in California long ago.
1300.00 bucks I'm pretty firm on price but let me know what you go and i might be willing to accept your offer.
