I need to get replacement cranks and a lock lever for a casement window but have no idea who the manufacturer is.

Your lock handle looks like the one on our 38-090, and your hinge is similar to our 36-048, but I'm not sure about that operator. It looks close to our 39-387 and 39-388. Look these over and see what you think.
