SWISCO - The Replacement Hardware Authority

Do you have this single arm crank operator?

A home owner from Sonoma, CA says:
Hi,

We just bought our home and need to replace one of the single arm crank window operators. The house was built in 1962 and I believe this is an original. The second photo attached is actually a different window operator, all but two of our windows have these newer types of cranks. (I didn't realize they were different until I removed the broken one).

The only markings are a "Pat. App'd For" stamped on the bottom of the unit and a "Parlyn L.A." stamped on the bottom of the gear.

I'm not sure what measurements you'll need, but I'll send you whatever additional info you need.

Thanks so so much,
Libby

Hey, Libby, thanks for posting. How about our 39-030? Could this be a possible match? Carefully compare it to your hardware to see if this can work as a replacement.
