They are Starclassic Performer, most likely 100% Birch, but dare I say, not definantly.
This finish is Transparent Black and was offered from 2001, which was the first year that the Performers were all birch. Prior to that the Performers were Basswood/Birch shells from 1997 to 2000, and are identical in a cosmetic sense to your drums. Performers actaully came out the year Starclassics were introduced (1994), but had other, more obvious differences until 1997, when the bass drum hoops were made of wood. Prior to that they were the Accutune ones made of plastic.
There is a way to tell the Basswood/Birch and 100% Birch shells apart and that is to look at the ply layup of the shell. Both shells were the same thickness but 8 ply for the toms and 9 ply for the bass drum in the Basswood/Birch configuration. 6 ply for the toms and 7 ply for the bass for 100% Birch.
Your drums don't have the rubber lined claw hooks or the sliding bass drum mount that were introduced in 2003, so your kit was made before that.
All in all, the likelyhood is that they are all birch given the Transparent Black finish, manufactured between 2001 and 2002, but if you want to be sure, count the number of layers in the shell.
