Rebuilt Engine

Spent the last couple of days putting a rebuilt engine in to this. Very different engineering to modern cars....
Any guesses what it is? Don't often get to work on a car that's even older than me.

Is that Austin 7?? I've put one of them together once... Although This engine was bit upgraded with bits like valve guides and seats. One we've had was 1927 year ans still original paint on it, Owner refused £25k offer for it....
