[Motorola] What does SGEID mean?

[Tom B]

HI Gary,

that looks like a public utility identification property stamp. Perhaps
>your equipment was purchased new by some gas & electic company and a user
>property ID option was ordered with the equipment at the time of
>manufacture. At one time this was an economical option.

It is part of the nameplate, not stamped on.  It looks just like the 
USGEID labling on encrypted radios but it is missing the U.  It looks 
like the U was never there.
