| Serial numbers were not used. |
| Engine numbers were stamped on the crankcase just back of the right hand bank of cylinders |
| and on a plate on the dash. |
| Engine Numbers followed the pattern of two numbers, a letter, then a sequence number |
| The first two numbers represented the model (in this case '55') |
| The letter began with A and ended with S |
| The sequence number began with 1 and ended with 1000 |
| Thus 55-A-1 through 55-A-1000 |
| 55-B-1 through 55-B-1000 |
| 55-C-1 through 55-C-1000 |
| The sequence continued until 55-S-1 through 55-S-2 |
