Gentlemen, thank you all. A lot of good information to digest.
Here are pictures a true Tech Rep cap badge. I do not own it so cannot give the dimensions (see 3rd picture).
From this picture that I found on line the tech rep badge does seem smaller. Perhaps the 1stASHG obtained those???
This link may also be of interest as to who the tech reps were.

This has been interesting and gives me the impression that determining a genuine 1ASHG cap badge is more than a little difficult.
