Answer
Hello Don.
  There are four models of this pistol. Each had their different details, which identify the model. If you could post a clear picture of the left side, I may be able to identify it. The ammunition should be marked .32 ACP. The brand of ammo does not matter. I will wait for your picture. Thank you for asking for me. Charles Gage
