Auburn is an old name in ;plastic farm toys. I have a survivor Auburn truck that I got as a Christmas present in the early 1960s. I have an Auburn tractor somewhere too but could not locate it for a photo. This "Barr" tractor and trailer is a reasonable facsimile. Obviously it endured a lot of playing in the sand box.
