Weathershield Crank Handle in White

Good afternoon.

Would you happen to have Crank Handle that can fit this Weathershield Window. or suggestions where to get it? Crank handle in white. Even a good used one if not made any more? Windows about 15-20 years old I believe. I had someone contact Weathershield and they don't have exact match - slightly different shape but only available in Goldtone and very expensive ($60!). Many thanks.
