dont know anything about sax, how do u find the key?

ok, i got a sax from a friend and its a conn 20m serial #:4240296. i was trying to sell it to some guy and he said he needed to know what key it was in. as an alien to woodwinds, as well as many other instruments, i had no way to tell, and was wondering if this site full of experienced sax users could give me a hand on deciphering the key. is it model specific? or does each model have several keys? and if so, what distinguishes it from the others other than the key itself?

It's a Conn 20m, so I guess it's an Alto sax, therefore it's in the key of Eb.
