Understood.

Also, I was reading somewhere else that the SC prefix was used through 1918. Or did they use this stamping after 1918?

I had also read that the clover stamping is another indication of Signal Corps. Is that accurate?

I don't know the answer to how long SC numbers may have been used, but I've seen some props that certainly suggest that it may have been considerably past the 1918 dates.

Might be a good research project.

No problem. Yes, that would be interesting to know more about.

Also, curious if you have any knowledge on the Signal Corps clover shaped stamp? It reads USA 76 inside each of the legs (U) (S) (A) (76)

I suspect that it's an inspector's stamp, and 76 identifies the inspector. That's often the format in other countries.
