Cars that fit in your pocket and also makes you go out of pocket

bioramaniThese scale model replica cars are 1/43 times the original. For the life of me I do not understand why 1/43? Exquisitely detailed and probably very expensive (Not @ 1/43 scaled down price perhaps!) these are engineering marvels in their own right.

As per my knowledge the design corresponds to 1950s to 1960s. It mimics an American automotive of that time. Body frame is made in steel rather than Aluminum used nowadays. The car which is now downscaled must have been a sensation during its time.

But now downscaled to 1/ 43? What does it mean?

These are small models for collectors.

Yes yes. But the number confuses me. It could had been 1/ 50 or 1/ 40 (a round number.)

This may help. It seems to do with European 'O' scale used for model trains.
