I'll try to not go into rediculous detail but here goes:
Black Beauty snare drums first appeared in the 1920s and had hand engraved floral patterns on the drum shell. These drums are quite valuable and bring some serious coin. The shell was also made of brass. These drums went out of production in the 30's.
In 1958-59 Ludwig introduced the Ludwig super 400. It was the early supraphonc and had a brass shell. The name was changed to supraphonic probobly sometime in 1960-61. The shells were made of brass until about 1962. These drums are kind of rare and bring in good money because of the brass shell.
Around 1962-63 Ludwig introduced the Ludalloy shell which was basically an aluminum shell that was chrome plated. Supras have been made like this ever since. Keystone badge ones fetch a little more than blue olive ones and they still make the same drum today.
Ludwig also reintroduced the black beauty in 1979 and made it for about 3-4 years. These are quite valuable now as well. They currently make the black beauty now with or without engraving.
This is a basic overview at best. I would suggest looking for a supra with the ludalloy shell. They made millions, they are reasonably priced and they sound great. They are perfect for classic rock. They in fact a very versitile drum. Hope this helps.
