Missing window crank from what seem to be original awning windows from a house built in 1968. Window and parts seems to have no useful markings on them, but the spline is too big to fit any of the cranks that I have purchased listed as 3/8". Looking for any assistance

Thanks for posting. Your operator looks like our 39-348 Sill Mounted Awning Operator. This is compatible with crank handles with an 11/32" spline. See our 39-205 and let us know what you think.

In case this helps anyone the handle that fit this was the Tee Handle with the 7/16" hole https://www.swisco.com/Crank-Handle/pd/Replacement-Window-Operator-Accessories/39-195

Had been looking for something that would fit for weeks so I couldn't be happier when this one fit and worked. Thanks
