The number 37 car I believe is from the Lucky Toy Brand and is in mint condition. The number 36 car has a very similar look, but I could not find one with a raised windshield or fin on the back end. This one has some scuffing and rust.
The number 12 car is from the brand ALPS in Japan, it is a Tin Friction Open-Wheel Race Car. It is in vintage condition with some scuffing and scraped paint. The left rear wheel is bound slightly causing the friction not to move forward.
I think someone with a little more knowledge would be able to fix it with some TLC and WD-40.
