Our house we built around 1975 or so. The front windows have wood casements and we need replacement crank handles. The pictures show the antique brass casement and handle. It looks like 39-114 is a match but we believe the bore/spline is 3/8" and not 11/32". Thoughts?

Thanks for writing in. Good eye regarding the 3/8" bore size. If that's the case, see our 39-104 instead. Look it over and see if you think this could work for you.
