LOL! Chris, thats priceless!!!
Good call Alan, I had completely forgotten about the British M1908, and that would nicely explain the MOLE stamp in that location, though most of these I have seen were stamped Wilkinson. Since Mole was in effect working with Wilkinson at that time for the India dept. seems quite plausible.
As noted also, the high tierce position in arm straight in cavalry charge would be well noted.
