Ralston Semi Trailer Truck Set in Box Vintage Toy high quality Trucks

Hard to find Ralston Semi Trailer set.
Consists of two tractors, a log hauler trailer w/ 3 logs, and flatbed.
Trucks appear to have had little or no play - I believe high quality they are 1/64 scale.
Box displays OK - has original insert - the tab holding the rear of the flatbed trailer has broken loose. There is some skinning to the outer box and a corner split, as pictured.
Hard one to come across - don't pass it up.
