The Kind Code serial number was not invented by IH.
ALL of the Kind/Code style serial tags follow this same format: Kind/Code/Country of Manufacture/Machine Serial Number no matter what country IH made the machine in. Translated, the Kind is 259, the Code is 009, The U represents United States (Country of Manufacture) and the 4452 is the actual serial number of the machine. For this example we will use the tag from the final Farmall-built tractor. The Kind/Code style serial number tag would remain in use for IH the rest of its existence.Ī Kind/Code style tag has the tractor model on the top line and the tractors Kind/Code information along with the country of manufacture and the tractors serial number on the bottom line. In the late 1960s, IH changed the serial number format on the tag to reflect the Kind/Code numbering system that IH had used to identify a machine since the 1940s. IH had a finish like this applied to the tag so that it would be legible for the machines expected service life. The serial number itself on the tags was always STAMPED, NOT engraved! The tags have a black anodized finish to them that is reasonably weather-resistant and not easily removed. They may even have a safety warning on them saying, “Do not overload.” In the 1940s, the engine data was deleted from most serial number tags. Early tags from the 1920s indicated the tractor model, serial number, and the rated rpm of the engine. Over the years, the physical size of IH serial number tags has shrunk, while the data they carry has grown. Counterfeiting and misrepresentation could be widespread if this happened. IH did NOT offer replacement serial tags even if they were listed in the repair parts catalog. There are of course exceptions to this and the exact location of the tractors serial number tag is always shown the in the tractors operators manual. IH started using this location for the serial number plate in the late 1930s and continued it until the mid-1970s. A very common placement of the tag was on the clutch housing of the transmission.

IH affixed the tag to a location on the machine that would be free from normal wear or damage from an attachment. IH did this to ensure that the tag would last for the expected lifetime of the machine. Typically the serial number tags were made of a rustproof non-corroding metal like aluminum or anodized steel. This was especially helpful to the dealer when looking up service parts to know exactly what parts may be needed for a repair. If changes or improvements were made to a machine, the use of a serial number would allow IH to note the change in the production run. International Harvester (IH) added serial number tags to their tractors starting in the 1920s to help identify the model it was and the number of its production. As time moved forward, corrosion and wear would often erase this marking. Some manufacturers chose to simply stamp or engrave the main frame or any other major chassis part with a production number or code.

As some Seiko movements were made for more than a decade you may end up with a couple of possibilities.In this original article, Red Power and Heritage Iron journalist Kenneth Updike details the ins and outs of International Harvester tractor serial number plates, from their origins in the 1920s as a replacement for frame and chassis stamps and engravings, to their enduring value as the most reliable identification of a rare machine.
This is how this tool works, I have collated the manufacture dates for as many Seiko movements as I could find which this tool uses along with the date code from the serial number. There are visual clues as to which decade the watch may be from but the easiest way is by using the Seiko movement number, if you can find the date range for the particular Seiko movement you are likely to be able to pinpoint the exact date. The letters O, N and D are used to represent October, November and December. As only 1 digit is used for the year this will only show you the last digit of the year, the decade cannot be found from the serial number, more on this later.įor the second digit 1-9 covers up to September.
The first digit translates to the year and the second shows the month. This serial number contains digits indicating the date. Seiko watches use a 6 or 7 digit serial number stamped on the caseback.
