Advice Needed: 30GOVT'06 Winchester Pre-64 Model 70

[82Trooper]

As I recall and I could be full of it, it’s US Government 30 caliber Adopted 1906. There were a number of 30 caliber cartridges for the military to identify them they were listed by year adopted.

so it does not denote any affiliation between the specific Model 70 marked that way with any government service....it simply identifies the proper .30 cartridge to use...?
