I picked this piece off an abandoned track in 1992. The pole was *mostly* down and there were about 10 of these off clear 214 Whitall Tatums on it. I grabbed what I safely could. However, this was the only one embossed WHITALL TATUM l0 10. The rest were embossed No 10 which is the correct embossing. I have never found another with this embossing error. This, along with all of the other wild finds I have discovered over the years is still in my collection today.
