parts for these awning windows

Thanks for reaching out to us! I'm afraid we don't know the brand of your windows. We may be able to help with the hardware but we will need to see a clear photo of each part you're looking to replace. For the operator, we specifically would like to see a photo of it completely removed from the window along with a clear shot of the top and bottom tabs, as well as the link arm. 

No problem. We'll be here to help!

Looking at the photo in your recent set of pictures, the operator shown would be a Left hand. As for the manufacturer of the window, I think it could be a very old "Florida" brand. However, I don't believe they are still in business or any of your parts are still available. We do carry two operators that are similar which would be the 39-256B left hand and the 39-257B right hand though. These are similar, but they do not connect to the side window linkage like your old operator does. These have a link arm attached to the gear arm on the operator. Your operator just has the gear arm only. I can't promise they will work so you'll need to review the specifications to see if you think you could adapt them to your window. 

We don't sell that long aluminum bar, unfortunately, but you might be able to pick up a piece of aluminum at a hardware store in your area and try to fabricate it yourself. I really wish we could be of more help but this window is very old. If you don't think you can adapt our operators to your window then it may be time for new windows.
