I. D. DATA

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
