Old Jalousie window cranks from 36"x60" windows

A quick learner from Saskatoon, SK. Canada says:
Is there a universal operator that will work if I cannot find the original make/model? I believe the windows were originally installed in a hospital that was demolished/renovated in Iowa in the early 1970s. They were then installed in our cottage in northern Canada.

Hello,

Unfortunately, we do not carry an exact replacement for the operator shown in your photos. We do carry a few jalousie window operators that we've related on this page but since they use split arms, we can't guarantee that they would work for your application. I'm sorry we won't be able to offer a closer match but please let us know if you have any other hardware questions. Thanks for posting.
