Does anyone out there have an asset which one might be able to look up a
vintage, late 1930's (yep... 1930's) name and callsign. In perusing my
parent's old marriage ceremony guest book, one fellow wrote "73" before
his name... Obviously (?) a ham..... I don't think QRZ can handle that
one!!!! hi! Tnx de K3HVG


What makes you think he was a ham?

After all, the greeting was used on the wired telegraph system. For
that matter, likely it carried over to commercial radiotelegraphy.

That doesn't mean anything, except that they may never had a ham
license.
