Vintage Tin Truck ?

This is one of my find's from this week while on r&r. It appears to be a truck , made out of aluminum with rubber wheels and steel axles. Looks like it was painted light green and yellow at one time, although alot of the paint is missing. It also looks like there may have been a trailer that attached to it, but it was not with it. I could not find any markings at all on this truck. It measures approximately 3 1/4" long, and 1/ 1/4" wide. I am hoping someone knows something about it, or maybe has a similiar one with the trailer . I am putting this under model cars because that is as close as I can get to toys. Why don't we have a toy category ?Thanks for looking and have a safe New Year's. Thrifty Gypsy
