clausen window crank handle

A home owner from Montana says:
13 45054 is on the handle of this Clausen window handle.
The large opening on the handle measures 11/16 and the smaller on the handle itself is 6/16 of an inch. I also need the base that the handle fits in.
Thank you!

Hello,

Your operator resembles our 39-015 Roto operator, which uses the 39-114L or 39-205 folding handles. One thing to keep in mind is that the spline and opening in the handle measure 11/32" in diameter. Double-check to see if these parts match up to yours. Thank you!
