Cool guitar, and they're not many of them loose in the world. You can solve a long-standing question for me, since you have the orignal pickups. What are they? Are they Gibson's Dirty Fingers pickups? Covers or no covers? I was in a guitar store in 1979 and they had several models from the Gibson "custom shop," which at that time was just skilled luthiers supervising short runs on the production line. These were runs of 250, the store had only one of each, and an LP KM like yours was hanging on the wall. It was the only example I've seen or heard of that was clearly, undeniably engraved "KZ" on the truss rod cover. Apparently meaning KalamaZoo instead of KalaMazoo. All other examples I seen pics of say "KM." My recollection is that it was basically an LP Standard with Dirty Fingers pickups. Other "custom shop" short run guitars had Dirty Fingers pickups: a Melody Maker-bodied KZ II with a clear finish over the mahogany and an SG Exclusive with a 9-piece neck and 7-piece body with seams perfectly visible under the black lacquer that was already sinking into the grain. I don't know why I bought it, as I really don't care for SGs. An LP Custom II was a weird mix of Custom level, mid-level, and economy-level features in a guitar called Custom, so I don't know what their goal was for that model. There was a badly-made Firebird with gold hardware and bleached mahogany body. When the "wings" had gone through the shaper to cut the V-shaped joints, both ends chipped out on both wings. It was put together with big globs of wood filler in the chipped areas, this being extremely visible under the clear finish. Classy!
