When I worked at Alstom Transportation in Hornell, NY, we had a substantial collection of old trucks, mostly roller bearing types, from different freight cars that most likely had been scrapped somewhere else.  They were used as shop trucks to put under transit cars we were building so they could be moved around in the shops.  I think almost every truck I looked at (sorry, no photos - we weren't allowed camera inside the facility) had raised lettering on it.  Some of the lettering had the bearing size, which determined the capacity of the truck, and almost every truck had the manufacturer's name on it in raised letters.
