Went to have inspection by local police of my Dad's old 50 1/2 ton, but the serial numbers don't match the title. Have the Kansas HP coming to investigate. He owned it for past 40 years, but would like to know if anyone has a list of serial numbers, as it may not even be a 50??? Here are the ## 5HP-E 15585 on truck, and title says should be HBA 590738 Thanks

The 5HP number is the serial number-It indicates the truck was assembeled in Kansas City (5)its a 1950 1/2 ton (HP) and was made in May(5)

The HBA is the engine number-Is correct for a 1950 truck.The engine number is stamped into a ledge on the block just behind the distributor.Clean and scrape the area and it will be seen.

Prior to 1955 many states used the engine number as the VIN number rather than the serial number.Evidently Kansas was one of them.

Have the HP check their ancient history.

Good Luck-print a copy of this reply also.
