Two Mercedes Benz Racing Cars below:

This one the very first version without racing number, no rivets holding base plate, and with white driver of 1936.

And this one the very last version with coloured hubs of ... well, I am used to date post-war re-issues of pre-war models with coloured hubs and crimped axles on 1950-1952. This one perhaps 1950 only, because of the old herringbone type of 'Dinky Supertoys' tyres.

But ... literature says that the die for this model was used to produce the French no. 23c, between May 1949 and 1951.

Could someone help me explain?

Kind regards, Jan Werner
