The pattern is the same as the original Winchester 21 Grand American. Standard engraving patterns for the 21 were 21-1 21-2 21-3 21-4 21-5(the rarest)21-6 & 21-6 with gold. 21-6 with gold became the Grand American engraving pattern after 1960. Of course, Winchester would do anything a customer wanted in the way of engraving if they were willing to pay for it. Typically, Winchester custom shop engravers did not sign their work unless the customer specifically asked for it, and I assume Tony is following this tradition.
