1991 R540LTD neck pocket stamp
I just picked this up. The serial number on the neck indicates it is a 1991, but it is a Wizard neck, so I presume it was swapped with an S540 of the same vintage, as the 91 R series had the Ultra neck. Does anyone know what the stamp in the neck pocket indicates? H&S 01R - 1H. I know H&S indicates it was assembled in Bensalem, Pennsylvania. I assume the 01R indicates radius, but his has Hum - Single - Hum configuration, so I don't know what the 1H is for. Anyone know?
