Hello Alan
Many thanks to you! - as always - for filling in the dots about the Midget.
Accuracy is important in a world of myths, I guess.

The amazing thing - for me - is that the commercial version had fan cooling!
Motorcycle and lawnmower versions were more simple... it seems.

I think I now understand that the 'sunburst' barrel casting preceded the straight fins.
It would appear that the 'beehive' fins are unique to the Atco-Villiers.

What an odd post ... to an outsider.

Cheers
