Since I was on the old interwebs today, I would like some assistance as to how to decode the VIN stamped on the upper firewall.

The truck is a '48 F6

7SR25 D2552

It is interesting to note that the 5's are of a much larger font than the rest.

Thanks in advance!

 

7 is the color code. SR is the assembly plant code for Somerville. 25D is your assembly date, April 25, 1948. The remainder is an internal plant rotation number, which means nothing to us.

 

Thank You !

 

Wait a minute.
Somerville, as in Somerville MA? This truck has spent it's entire life in MA!!?? That's impressive.
As for the paint code what color is a 7?

Is all this info somewhere I can look it up myself and not bother anyone?

Unfortunately the catalog doesn't list states next to the cities in their code chart. But since larger trucks like the F6 weren't geared for highway use, it's not uncommon to find them not traveled far from home throughout their life. They typically went from farm to market and back, and consequently they have low miles and in relatively good condition compared to their little pickups brothers, used and abused.

But I did find this tidbit of history...

Still visible on the firewall. Thanks!

 

I saw that too and wondered... I know who the truck was delivered to new in Chicopee. It sat for a long time and then I became the owner. I am technically the 3rd owner. But the middle one didn't do anything except resell.

 

Concur.

A good rule of thumb, is that the larger the truck, the lower the miles, and generally speaking, the better the condition. I have seen numerous larger trucks of all makes with surprisingly low miles. The biggest factors that seem to determine condition are whether the vehicle was maintained, abused, and time spent outdoors.
