I guess Grade-0 is the Trojan, which according to my 39th Blue Book wasn't introduced until 1912-13, well after mine was made in 1892, and Grade-1 is PH or VH?

There is what looks like a "V" in the first picture, if that means anything (lower left in picture).
Is the "Serialization book" on-line or where do I look for it?
Thanks,
