Symbol meaning

That listing from The Parker Story doesn't include the marks found in the barrel material location on the right barrel flat of the early Vulcan Steel, Titanic Steel and even a few Acme Steel barrels. On the Titanic and even a few Acme Steel barrels the mark is a K --

These marks were in use up into the 134xxx range. By the 135xxx range we begin seeing the T, A, and V in a circle.
