1952 R. Andersen Corporation Casement Windows

A home owner from USA says:

I have casement windows with internal mounted screens without cranks, which makes it very inconvenient to open the windows. These windows are original to the house, which was built in 1952. The hinges have engraved on them "R. Andersen Corporation Bayport MN". Ideally, I would need 30 hand cranks to accommodate all windows, but costs may prohibit me from doing all at once.

Please review the pictures below and advise if you have a hand crank that would fit these windows.
1. Window closed without screen.
2. Window opened without screen.
3. Window opened with screen in place.
4. The engraved hinge showing "R. Andersen Corporation Bayport MN".

This is a very old window. I'm afraid there is not a direct replacement operator for you, but I have a couple ideas. Start by looking at our 39-015, or maybe a lever-type operator like our 39-069. These operators come in different sizes, each of which is its own separate product you can find in our catalog, so look over your dimensions and see what may work.

Take note that you will likely need to have a contractor or carpenter make up a new sill cover to accommodate the screen and notch out for the operator.
