Does anyone recognise what engine this rocker arm might, possibly, be for, please? I did wonder if it might be for an aircraft engine but I'm not so sure now. Many thanks.

That looks very similar to the rocker arms on a 1964 Volkswagen Beetle I once owned.
The forked end for a looped push rod is interesting.
Just a guess, but more likely a rocker from an OHC engine that's missing the roller and pin. - Bob
But, here's a link showing similar from a pushrod type aircraft radial:
Rocker Arm Jacobs R-755 Radial Engine Vintage Aircraft Spare Steampunk | eBay
It's on eBayUK - item#323806811562 if you can't get it to open.
Cam roller... sounds pretty plausible, and more likely.
Thanks for the replies chaps. It did come with a few aircraft related bits, hence I thought that it might be aircraft related.
I would have thought maybe it came from a crashed aircraft local to you, you guys had enough to choose from at one point.Quote:

I think you got it right in your subsequent post Low & Slow, the rocker arm is missing the cam roller. You find cam rollers when the cam lobe is directly contacting either the lifter or the rocker arm. Since this rocker arm utilizes a cam roller, it must be from an OHC engine unless there's some sort of valve train I'm unfamiliar with.Quote:

Bring in a metal detectorist to go over the property and you might find something much more interesting. ;)
IN could mean it's an intake rocker. - Bob
