Technical 1940 Ford Sedan - What does this mean?

I found this stamped into the upper portion of the firewall on our 1940 Ford Sedan project. Just out of pure curiosity, does anyone know what this means?



Thanks for any insight!

I believe it's only the body number...

 

It's number 710 (seven, one, zero)...and don't you forget it..!

You're reading it upside down. It says "OIL".

 

Thanks guys!

Did not think it was anything important I was just curious...

Now I know - add OIL! hehehehe

 

you all have heard the joke about the 710 cap on a motor,this is the really old version.
