Did you go to the Slingerland information? With the badge and serial number you should be able to get a close year on that drum...
Once you do that, then tell us the year..
The drum at one time in 1978 was called the "Sound King" it had 8 or 10 lugs...
In the 1973 catalog it was called the "Gene Krupa Sound King" and it had 8 or 10 lugs.
The exact same drum just had a different name..
So please tell us the year of the drum based on the articles...
There is no reason to find the info on other web sites, just tell us the information about the drum you have and then we can help you..
Thanks and yours looks like the shell is damaged from steel wool and some big dents on the butt and lugs?
Does a magnet stick to the shell? It should be COB, so it will not stick
