Looking for help on what the barrel dimensions are for a standard type III pre-64 model 70. I'm looking for the barrel diameters all the way down to the muzzle, including the rear sight tumor. Thanks

This is for a .270 barrel....

thanks

I have a take off..sell cheap...PM me

If you want a new barrel with pre-64 dimensions, in the past I have bought barrels from Douglas which match the Winchester profile and fit the inletting of the factory stock perfectly. I presume they still offer this service.
