I've looked all over my H3/HD3 Allis Chalmers for a serial number but cannot find anything that correlates to a serial number. I'm sure this tractor was made in the 1960s but I can't find any indication of the number of hours on the machine. Sharing this photos in case anyone understands what it means -- DC23S is imprinted on the right side (pictured). 11913 is engraved on a plate behind the blade. GDN16802 F on the muffler or exhaust. . Hoping to list this for sale.

| That’s a casting number. The serial is stamped into the bell housing of transmission where it bolts to the engine. Should be on upper left side as you sit on it. |
