My, my, that is an old lens. Aperture on one of the dials and shutter speed via a spring-driven mechanism on the other. I've seen a lens like that but for the life of me I can't remember what it was attached to, but a Twin Lens Reflex of some sort comes to mind, might be wrong though.
'tis a nice old lens. I've no idea what, or by whom, but nice all the same.
Interesting to light from the left while having slightly greater DoF on the right (at least that's what it looks like to me).
