Well I tried AA first this time then about a dozen searches on the internet and came up with zero. The 19 and the dots on either side are front and center just like a mfg. embossing would be with the sizes and DROP FORGED U.S.A. on what I would call the back OR maybe it's the other way around. Photos attached. TIA again for your help.
STILL Newbie Charlie
Kinda looks J. P. Danielson.
Vlchek would be my guess.
