I seem to remember a JTC quote saying the first 99G was about 237,500 - which according to Murray's is the end of 1921.
Curious about when they were introduced. Looked a while back and the first ads I could find were for the combo kits in late 1921, and the first catalog/price list I know of is 1922 - which calls it the new 300 Savage cartridge.
But those dates conflict with the timeline of 1920's being made in them in 1920.
So what's the campfire got? I'm afraid I don't have any early ones and no notes on them. Earliest I personally know of off the top of my head is 245,xxx - which I'm sure isn't the earliest.
