Having been away from the forum for quite a while, I figured to check back in. Low & behold what's at the top of the page? My favorite subject of debate......Black Panther finish! :)
A few things to point out about BP........the mod finishes that may be hiding under BP would only be on 3-ply shells, not the later 6-ply like those in the first post, and they most likely would have been very early 70's at the newest. So please don't bother trying to "look" under a 6-ply for a rare mod finish. It just ain't there! ;)
The last catalog that BP was featured in was the '75-1 catalog. Now I personally have seen 6-ply BP on a couple of occasions, but they all seem to be from around 1979. These with the modular mount would put them to oldest 1980, as that was the first year for the Modular castings.....not the mount, as those came out in '78, but the actual castings as shown in the first post. Early modular mounts used the "classic" bass mount on both the bass and toms.
Could BP have been available as late as '83? Sure, but I personally haven't run across any yet. Hey, its Ludwig, anything is possible! :D
