metal cars

I remember these being at my grandmothers house. I know nothing else about them.

They're too flimsy to be toys, so they must just be display pieces. Each car is appx 1.25" - 1.75" depending on the car. The shells are a cast metal and the wheels are plastic. The plastic base says "Japan" and "TM". The labels are stick on. I don't see any markings on the cars themselves, but I didn't remove them all. They're held onto the base with a red pipe cleaner.

The 8 cars are (in no particular order to the pics):

1908 Fort Type T
1769 Steam Car
1886 Three Wheeler Benz
1892 Duryea
1896 Oldsmobile
1900 Locomobile
1894 Heins
1885 Daimler Gasoline Car

The last pic is a close-up of my fav 2...the Daimler and the Benz

That's all I've got!! Any information on them would be greatly appreciated. Maker, age, etc.

THANKS
