Buick Bubaa's

Need some assistance on a buick body code.
Guy says its a 1952 Super 50?
Pretty sure its a 52 series.
Bounced what I could off this site:
http://www.buicks.net/years/52.shtml
Heres the body plate.

Any help appreciated!

 

who's Bubba?

 

Thank you for reaffirming my spelling handicap. Meant it towards people knowledgeable on Buicks. Call people bubba's some times? Why don't know?

Forget there is a spell check on here.

 

All he's saying is it's a Super, the Super's are 50 series. The 2 merely adds that it's a 4 door Riviera...

 

Forgot to update.. sorry, and thanks Zman didnt know that before, but figured it out. Know that the trim code is 52-51 Dark Grey Cloth-Light Grey Bolster
Still trying to find the paint color code. No: 21?

 

21 is Sky gray upper and Surf blue lower...obviously a two-tone car...
