Sound knowledge there mate! I always knew them as "Metropolitan". I didn't realise that they had anything to do with Austin until I started searching for the photo's on the internet. They weren't a typical "Austin" car were they?
My elder bruv had one of these for his first car...

Same colour but without the false eyelashes! An Austin A35 van.
It had semaphores, not indicators like the one in the picture, Although he had the indicators fitted later. It had one of these in the middle of the dashboard...

That's the indicator switch and you turned it right or left depending on which direction you were turning, the red light in the middle would blink whilst the indicators were on, and it didn't self-cancel. Indicators were called "winkers" back then - this may be why? It looked like an eye!
It was a utilitarian bit of kit was the A35 van. Bruv worked on a farm so it was dead handy for lugging sacks of spuds, or transporting rabbits, chickens, hares and turkeys from farm to kitchen table. It was also handy for transporting the Jack Russell terrier when we went rabbiting or fox-holing.
If I recall (and without consulting wiki) it was a 998 side-valve engine. Capable of 0-60 in less than a week. Sturdy and reliable.
