Here is an example of difference between diecast scales,
around the 1981 Citroën 2CV Charleston.
1/43 is very popular in Europe with many manufacturers.
At different costs, you can also find absolutely all car brands at this scale.
1/148 or British N gauge is much obscure,
reserved for model railway collectors.
Finally 1/64 our favorite scale, that continue to grow worldwide
(for Europe see the upcoming Schuco releases
and a announcement of a new batch of Solido by Kyosho).
Not too big, not too expensive and well detailed...
