We have 9 multi-pane and 2 single-pane aluminum awning windows from Victor Windows in Philadelphia installed in our summer cottage on Lake Ontario. (The company is out of business.) I need several new operators. The old ones have the same specifications as your Items # 39-025 and 39-026 with one exception. The arm extension on my operator measures 2 3/16" from the threaded bushing to the riveted connector, hole to hole. The same dimension on your replacement operator measures 2 3/8". Incidentally, the inner arm from the riveted link into the crank measures 2 5/8".
Do you think items #39-025 and # 39-026 will work in my windows?
Thanks for your advice.
Chuck
