The history of the spring horse goes hand in hand with that of tin litograph horses. The heyday of this toy was reached between the 1940s and the 1960s. A spring system and saddle were able to shift the weight to the legs, making them move just like a real trotting horse.
The cheap price of tin and the life like movement of the horse made this toy a big hit. The largest manufacturers were based in Germany and the UK where D Sebel&Co made the famous MOBO horse.
