Cylinder flow 22mm, return 15mm into what looks alot like an angled rad valve. Has same (?) 3/4" fitting before going back to 22mm. Those sizes may be imperial as its a 1971 arrangement. The valve has no spindle head but a screw inside and a little plastic cap. I've seen it discussed somewhere- I wish I'd paid more attention! Any help please.
What's this valve for?

Sorry Kev, didn't get a pic and won't see it again until end of week. What be a 'cytrol' then? First glance it looks like a rad valve on the return from the cylinder- then realised it wasn't quite!
