Researching the Primer Timeline for the 44-40

[Savvy Jack]

If I have posted such information before, it shows just how bad I am loosing my mind!!

Reading tracks in books again, I am trying to put together the Primer Timeline for the Winchester 44-40 cartridges here:
https://sites.google.com/view/44winchester/chasing-the-44-40/cartridge-details/winchester/primers

and in google docs here:
https://docs.google.com/spreadsheets/d/1Jy0pGqWPRx2HOQqufbcnEM1lv6tCWBJsCOB8vLIDOIg/edit#gid=462843466

There should be at least eight different small primers used in early 44-40 small primer cartridge cases for normal and W.H.V. loads

1. Oval Small Primers

Copper - no stamp
Copper - W (over-lapping V)
Copper - W (inside a circle)
Copper - W
Brass - no stamp
Tin - W (over-lapping V
Tin - W
Nickle - no stamp

2. W.H.V. Loads

Oval Small Primers
Copper - no stamp
Copper - W
Copper - Large W with Serifs


At least lists two different large primers used in late 44-40 large primer cartridge cases for normal and W.H.V. loads

1. Oval Large Primers

Nickle - no stamp

2. Flat Large Primers

Nickle - no stamp



Any help with Winchester primer box dates, photos, primer photos, Patent data and photos would be greatly appreciated
