The next two numbers designate the month in which the engine was built. The following two numbers designate the actual day the engine was built. in the example this engine would have been built on August 19. NOTE; In 1958 the Month Code could be either one or two numbers to designate the month, example January could be represented as 1 or 01.

The Engine Suffix code is either 1 or two letters and these tell what application the engine would be used in. Use the Chart below to decode the Engine Siuffix Code.
