Hi Mike, on the other board when I said yours looks like a M114, I was close its really a M113 I believe. Im not an expert on them and forgot about the series having the 2 ACC numbers...
Here is another one signed that is heavily trimmed that I believe is really a M114 issued well after 1910 ??? But was called a M113

Maybe someone who is an expert on these M113/M114s can positively ID your pose from the 1910 issue and not one of the later ones issued in the 1920-30s
