Adjust Infinity Focus on Pre-36 Iscorama Taking Lens

I've never actually used the 50mm f2.8 Iscorama taking lens with the Iscorama adapter, but I assume it's meant to be focused at infinity–like other lenses.

(Correct me if I'm wrong.)

It's way off. The image is very out of focus. And adding a lens mount adapter, as I plan to, has the potential to throw it even further off.

I assume there's a way to adjust it? Using a spanner wrench or something? I really have no idea. Help.

Anyone else had this issue?

So it looks like it's focused past infinity. I can remove the set screws up front and it just takes off the part of the lens where the adapter attaches. But doesn't do anything to the optical assembly. 

I think I see two areas where I could turn the optical assembly with a spanner wrench. Is it as simple as that? It's front focusing by quite a lot. Thanks!
