Just bought a Rodenstock Sironar 210mm with Prontor Press shutter on ebay.
What is this adapter / ring for? Never seen this before. Is it for mounting the lens on the lens board a bit further away or?

That's a spacer ring. They're usually found on #3 lenses. It's nice to have if you're using the lens on a field camera, where the uprights on the lens panel might prevent the lens from being mounted, or the controls are obstructed.
