LP12 - identifying Cirkus bearing


I need to know how to identify the Cirkus bearing upgrade on an LP12. Is it possible by looking at it??? Trying to buy one, but the seller is not sure if it has it or not. The serial number is just over 80000...thanks

It appears the Cirkus was added starting in 1993 with serial number 90,582.
