The question of first licensing makes me wonder?  From a legal 
standpoint I don't think this information carries any 
significance.  Isn't it just a bit of information to be a part of the 
exchange?  I've not checked the FCC's database so don't know if 
anyone can check on the fact that I got my callsign/license in 
1957.  Sadly along the way I've lost the original paper document.
So, I'm wondering if you weren't quite sure of when you got that 
ticket, wouldn't an approximation do about as well?
Thanks for the upcoming opinions.
