Model 400 from 1948. It might also be a 401 as there were only minimal differences between these two (at least in Farina version). Recently I spotted one VMG 641 on the highway near Antwerp, Belgium. It might have been at the way home from the Mille Miglia. When I looked for it on the internet I found it was a participant of the Mille Miglia.
That's it, yes.
They made a small handful of these 1948/9 with some minor differences but this is an early one from 1948.
I'll post some more pictures later.
So that makes you an Expert!
Well done, but of course it means you can no longer participate in Rookie puzzles, just Expert and upwards.
But it does mean you may post your own puzzles if you wish; hope we can look forward to some.
