Newbe Question JD 450BA

[shullpeter]

I just bought a JD 450BA and am trying to ID the year so I can get a service manual.
Also, any ideas where to get a manual

Data:
JD 450BA
What does the B and the A stand for?
Serial No. 132787T

Engine has 2 numbers:
4219ct02
198851T

From a previous post I found this info but don't quite get it as there are no no. asso. with codes 1 through 6.

Explination of Type Codes per SM 2064
Basic Tractor Serial Number Explanation

1 2 3 4 5 6 7
| | | | | | |
T 5 F 3 M xxxxxx T

1. The first letter designates the application T = Tractor
2. This number designates the series 5 = JD450
3. This number designates tractor style C = Crawler
E = Crawler Loader
F = Crawler Dozer
4. This number designates the fuel type of the engine 1 = Gasoline
3 = Diesel
5. This letter designates the type of transmission C = Collar Shift
M = Hi - Low Reverse
6. Sequence serial number of six digits Differs for each engine
7. This letter designates the manufacturer T = John Deere Dubuque
Tractor Works

Anyway, any help would be appropriated.
Thanks
