Duh! I just realized the sword in the scabbard is almost exactly a yard. All I need to find for a comparison is a yardstick and a someone around 5-6 to compare to the photo. I wonder if I can manage to find someone that size to hold a yardstick for me?

THANKS BILL FOR THE MEASUREMENTS.

Having his height might help narrow the search to identify this soldier somehow. I can't tell much from this photo about the bars that you asked about Bill but I will see if the original is clearer in that regard. Thanks.
