Weatherstripping for Malta Casement windows

A home owner from Alpena,MI says:
I have 1975-76 Malta casement windows. The window frames have a fine grove around them in which thin metal strips ( weather seals) are installed. What can I replace it with. Also, I need 4 to 6 operator replacements. Any ideas?
Thank You, Chuck

Hello Chuck, thank you for posting on the discussion board.

You may want to begin looking at the Swisco 55-106 Weatherstripping. For your operators, we recommend uploading a few photos so we can take a look. That will help us in researching a replacement. Please be sure to include dimensions and any markings you may find.
