Solved: PN #359 -- Pozzi and Comino's Romi Isetta based racer, 1957

[pnegyesi]

I am not sure it had a name, so for a point I'd like to know: country, year and donor. Easy, isn't it?

No on all 3 counts

[pnegyesi]

Professionals?

I think there was a category proposed in France for 3-wheel 500cc racing cars in 1950s (I have marked them as Racer 500-3, following web info). So this may come from France or, say, Morocco.

[pnegyesi]

way off the mark (not Europe or Africa, not to mention the engine)

[RayTheRat]

I saw cars similar to this race in Morocco.  The only photo I have of something similar is of a Panhard-engined 4-wheeler (Formula 4, I guess...it was 1971...see attached photo.)

But since that's not it, how about Down Under: Australia (New Zealand will be my next guess if it's not from Oz.)

[pnegyesi]

Morocco was mentioned previously. Not from Aus or nz

[faksta]

India?

[pnegyesi]

No

[faksta]

Hm...Argentina? They've had a thing called Formula Mini Junior, but I'm not sure this one would fit technically.

[pnegyesi]

Getting closer

[faksta]

So, as I get it, we're talking about an American continent. Southern part of it?

[faksta]

Oh, wait, is it based on a Brazilian Romi Isetta?

[pnegyesi]

Give me the year and the point is yours. Obviously locked for you until your next reply

[faksta]

A bit of a wild guess: 1959?

[pnegyesi]

you have one more guess before I reluctantly open it up again. Still locked. (Difference is more than a year)

[faksta]

The car dates from 1957. Designed by Silvano Pozzi and Emilio Comino.

[pnegyesi]

that's more like it. And another point for you
