Ser.h.7215

[royprop]

I have a wooden propeller with the markings SER.H.7215. I saved it from my father's chain saw about 35 years ago as he was going to cut it up for carving wood. Interested in the history or any background on this great piece. At some point, someone fabricated a clock and placed it in the mounting hole.

Something doesn't seem right about the stamping.

Can you post a photo of the prop and a close up of the stamped information? Is there anything else stamped on it?
