We have been watching Rogers come back to life lately, Slingerland is now in DW's hands and we shall see what happens with that. We did see Leedy snare drums for a while. Ludwig and Gretsch never really went away.
But of the remaining most popular American drums, Camco will probably not come back even though the were great drums and have risen to command very high price tags in the vintage market. After all, how can you resurrect Camco with lugs that look just like a DW? In the end, you Camco guys will have something very unique in vintage drums.
