Hello everyone!
I am helping my friend restore this GMC 2½ ton truck from 1943 and found these original markings under several layers of old pain.
The number is the same in small and large nr:s and is 474919.
Is there anyone who knows how to track this backward to se what company it belonged to during ww2?
I know it has been in the norweigan army since the war and then sold as surplus several yeats ago.
Now we are restoring it to be used by our reenactment group big red one sweden.

All the best!
Joakim from Sweden
