Bobdahunter & IDG397: I have 6 pre-64 Winchester Model 70's in my collection in caliber 264 Winchester Magnum - 4 are Standard Rifles ("Westerners" - no recoil pad - just a buttplate) and 2 are Featherweights in 264 Winchester Magnum - they both have factory original recoil pads.
Long live the Riflemans Rifle!
I am leaning strongly to the "invoice"/"receipt"/Rifle being legit.
Many Model 70's appear to have been "manufactured" from on hand parts etc, at the factory, well after they quit being "cataloged".
Hold into the wind
