I need operators for several wooden awning windows. Most are 39"wide by 24" tall. A few are 47" wide. I haven't found any markings on the parts but the cranks seem unique in that they have a hex post that fits into a female socket in the operator. Probably 1960's vintage. The screens had Andersen markings but nothing etched on the glass. Single pane glass with interior screens and exterior storms.
The two lever arms are about 17" long and the track is 36 1/2". I can get more photos if that would help.
Thanks,
Jeff K
