When I had the chance of a lifetime to meet Tommy Shaw of Styx fame and we got to get a pic with one of his guitars, he mentioned that he calls his Historic "Bertha" because it's so heavy. So when I got my Trad Pro II, I call her "Baby Bertha

I googled patent 2,737,842 and wiki came up with http://en.wikipedia.org/wiki/PAF_(pickup) "After about 1967, the original PAF design changed. These pickups are referred to as "Pre-T-tops". Gibson began to stamp the patent number on some PAF stickers after they obtained a patent (U.S. Patent 2,896,491) for the PAF pickups. Most humbuckers were labelled with U.S. Patent 2,737,842 until 1962 and the number shown on the pickups, which actually is a patent for a Gibson trapeze tailpiece bridge and not for a pickup at all. Both true PAFs and incorrect patent marked PAFs are fairly rare today and make an expensive vintage collectors item."
