I have a question regarding the dates of different UMC .30-30 headstamps. From what I can tell, there are three different variations of .30-30 Win. headstamps by UMC. These different headstamps range in date from around 1895 until after the merger with Remington.
The earliest variation:
U.M.C. 30-30 S.
The second variation:
U M C 30-30
There are also 4 different loading available in the UMC catalogs:
.30-30-100 Win. Miniature (first appeared in the 1903 catalog)
.30-30-117 Win. Short Range
So my questions are: When did UMC transition from the earliest variation headstamp to the second variation and from the second variation to the third variation? Did the transition in headstamp occur for each loading at the same time?
On a side note: I have also seen an early UMC box with the headstamp designation of U.M.C. .30-30 MARLIN, but I have never seen an actual round with this headstamp. Does this headstamp variation really exist?
On another side note: does anyone have a round with the headstamp U.M.C. 30-30. (second variation) and a .175" diameter copper primer with an impressed underlined U?
Thank you very much and merry Christmas
