Joe,
A minute point but Gail White used at least "1" black spacer, sometimes more and I have a letter he wrote to Grady stating such and "why".
I was set up with Tom at a Miami Beach Convention Hall show where he sold a confederate, highly engraved and checkered and no "TL...or "L" or "Tom Leschorn". I'll admit he signed a bunch...but, according to Tom, a dozen or so were not.
FYI,
Capt. Chris
