I got this 16" floor tom several yrs ago with a 60's Black Oyster Pearl kit I bought.
It has no vent hole, therefore no grommet or badge. It has 2 holes similar to Ludwig muffler holes, but they are slightly larger holes than the ludwigs I have. It was originally WMP but someone got creative with paint all over it. The legs are straight and the lugs don't look familiar to me.
It has a clear maple interior with re rings. It has a stamp inside that looks like something 1966 and a "P" stamped on it.
