Spring powered stainless steel and bronze toy car with walnut box.
Pull the car backwards while pushing down and the motion of the turning wheels is stored as energy in a coiled spring inside the big central toothed wheel. Let go and it unwinds, propelling the machine forward. When the spring has fully sprung, a clutch disengages and lets the car roll free.
Without a body, or even a cover over the engine, you can see exactly how the car works.
Sir, what’s the price n how to purchase this toy. Rgds
