B61 CHASSIS MARKINGS

[Rescued Dog]

 When I started to clean and prepare our B61 for painting, the original brown undercoat was in good condition and I was surprised to find various markings at the front of the chassis rails. There are stenciled markings which I can't identify.

I wonder, did Mack press the rails in which case they stenciled the markings or were they purchased from an outside supplier who applied the brown primer and stenciled the numbers on?

Also there were hand written numbers painted on above the stamped chassis number. As per the Chassis Sales Record these turned out to be the CSC numbers, so would have been put on when the chassis went on the assembly line. 

The B61 had a factory finish date of December 20,1963 and was shipped to Mack Australia in January 1964.

It seemed to me from working on 1945 Mack chassis they primered brown all or the most of separate parts. And when the chassis was rivited together and different brackets and attachments put on they painted it all over into the final color. With cooper tubing etc already in place. So all those hidden marks you discovered seem used as the factory internal id's. Pre-assembly markings or part numbers. No matter Mack stamped the rails or a vendor they should be id'ed coming onto the assembly line.

Interesting, thanks for sharing.
