Ertl John Deere Tractor 1357D & Trailer Wagon 1878G Farm Toy – 1/64 Scale?

Description

Ertl John Deere toy tractor and wagon
. Both appear to be made of metal (expect for their tires, pipes, etc.). There are numbers on the bottom of the tractor that read "1357D" and on the bottom of the wagon that read "1878G." My grandma used to own this and I inherited it, so I'm selling it for someone who can make use of it.
I am unsure of the scale (I'm thinking 1/64), but I included the dimensions in this paragraph. Both the tractor and wagon hooked up are a
pproximately 6 1/4" in length. The tractor itself is 3" long, 1 13/16" tall, and 1 7/16" wide. The wagon itself is 3 7/16" long, 3/4" tall, and 1 7/16" wide.
The top of the cab has a couple cracks. There are a few scratches, worn off paint, and signs of use throughout. See pictures for details.
Toy comes from a smoke-free, pet-free, clean house.
