My father had a Moskvitch 427 back in the seventies, his was Mustard Yellow with a black vinyl roof, I would love to find a similar model. I have two 1:43 models, so far, a white model Made in the USSR (no brand indicated on the model but maybe RADON) and a blue model by DeAgostini (Made in China). Both cost me 20 lari ($8.33).
The Russian made model has some chips, it is heavier and less fragile than the DeAgostini model. The Russian model also has an opening bonnet. The Russian model is clearly intended as a toy and the DeAgostini is a model for adult collectors.
The Soviet model has a metal base, the DeAgostini base is plastic. The DeAgostini has better detailing around the windows and the wipers are separate (but fragile). The wipers on the Russian model are just moulded into the windscreen.
The black interior of the blue Moskvitch makes for a better contrast than the white interior of the white Moskvitch.
My favourite would be the Soviet made model, it is more robust and has an opening part.
