Engine picture - what sort of valve arrangement is it?

[Carfolio]

Looks like overhead valves to me, but literature I've read suggests it to be overhead inlet, side exhaust.

Thanks!

It looks to me that the literature you have read is correct - two pushrod operated inlet valves per cylinder and one side mounted exhuast valve. What is it BTW?

Yeah, looking at it again I see only 6 pushrods. It's a six cylinder btw. It's a picture of a 1911 Chadwick Type 19 engine.

ETA: Thanks for your response! How rude of me to have left that out

Looks like an interesting project/research topic. I love engineering of that era, before there was a generally accepted way of doing something, people had all sorts of ideas which seem crazy now. Everything was made in-house, and tested for real rather than in a computer simulation.
