As for the start and stop dates... the latest production dates I've seen so far for the 1895's has been in the 1st half of 1897. The 1st 1899, per JTC, was 11/1898.
There were brl's used on 1899's with the Repeating Arms address but the 2nd line has the Oct. 3, `99 date. Appears someone just used the wrong roll die.
The "Cal. 30" in the address and "SAV 30" on the brl top was not used till 1900. The lowest serial I've heard of is 133xx with most in the 16xxx range.
A letter is finite till then it is a guess. As with Plab's 22" 1895's lettering as "Light" and "Lightest". 100 plus years for that info to come out.
