ball bearing turbo ?

[t-typinator]

I was told the turbo in my car is a ball bearing turbo.

Is there any way of telling by looking at it,without taking it apart?
I may be selling it soon but don't want to sell it as a ball bearing setup if it's not.
The guy seemed to be honest about everything on the car i just want to make sure.
It is a polished turbonetics with the gold colored back on the compressor side + has a sticker that says turbonetics turbochargers,+ T-21847 on it.
I can't seem to find the meaning of those letter/#'s anywhere.
Any help would be appreciated. Thanks.

btw
for future incase that link moves
T-21847 is the serial # and serials from T-20000 can be looked up by turbonetics to determine what they are

incase your serial is too old to look up the ball bearing turbonetics can be identified visually by looking into the oil drain and into the small hole and seeing if the cartridge is shiny silver , if it is its a ball bearing turbo
