1980 C-series Serial Number Location ?

[tractorbeast 27]

Is the ID tag under the Control Panel, where the SN would be located on a 1980 C-125. The tag is rivited on. The first number is the "Model number 01-12k801" than there is another set of four numbers. Below all of the above listed numbers is another set of four numbers. I'm thinking this might be the serial number?

The digits after the model number should be the serial number.

The numbers near the bottom of the tag should be the (Julian) date when the tractor was manufactured.

Example:

This is from a 1976 B-80 / 8 speed

S/N 24457 ~ built on the 181st day of 1976
