Greetings from Finland.
I bought the M715 model year 1968. I am starting to restore it. I would ask you if you have any information about tailgate marking?



The seller told me that truck likely was in the service at Fort Sill Oklahoma. And was surplused in the late 70's and donated as surplus to the Frederick, Oklahoma Fire Department where it was used as a back up fire truck.

Now I would like to ask about markings.
