Trying to find operator case and handle

Hey Mary. I don't believe your operator has been made in a long time. As such, whatever handle went to it originally likely isn't around anymore. The 39-114L remains our best and only replacement. Our best option for the cover would be the 39-107, but note that it clearly is for a different size so I'd have doubts it could work for you. Unfortunately, these are the only two parts that have any hope of fitting on your old style operator.

I'm not sure who else may have the old parts these days. If you can find a local mom and pop kind of hardware store near you, they may still have some in stock.
