heres the best i can get:
It's funny, but I had assumed the serial number tag I attempted to decode earlier was from the engine, because the numbers follow the same sequence as Perkins engines. Now that I have better pictures to work with I can see that I got a couple of numbers wrong in the previous attempt. The 8 should have been a 0 and the 4 should have been a 1.
OLD:3383 849497
NEW:3303 819497
However, I'm still having difficulty with the numbers on the bottom portion of the tag.
