Big-Bang Model 5T Motor Tank

The Big-Bang Motor Tank appeared in 1941 and was produced through the mid 1960's. Early models have unmarked tires. Later models have "ALLSTATE" marked in the wheels. A very few motor tanks have been observed with tires marked "AUB-RUBR.BALLOON Auburn, Indiana -Made in USA". This is the model I received from my Mom and Dad at Christmas 1957.
