I notice that my W.R.A.CO. headstamps appear earlier product than W.R.A.Co.
Same for R dot P vs R-P. Sorry no dot on my keyboard.
And U M C vs U.M.C.
Do the 2 different headstamps represent different manufacturing periods. Or just different factories or machinery?
I believe F is earlier product that FA - both Frankford Arsenal. Can someone give me the dates of manufacturer for the 2 styles.
Any chance there is a list on the Forum that shows the dates in operation for major US manufacturers?
