Fenestra operator

A contractor from arizona says:
I am looking for a Fenestra operator for a casement window. The one I am replacing is stamped 52-01 R on the bottom.
Hole spacing= 4 1/4"
Arm length= 9"
spindle= 9/16"
color is a natural aluminum color.
Even though it is stamped "R" on the back, it appears to be a LH as the crank is on the right as viewed from the crank side. Thanks, Neil

Dave Sr. from SWISCO responded:
It's hard to say what can work. Start with our 39-344 and 39-358 Fenestra operators and see if you could use these. If not, please show me a picture of your operator out of the window so that we can find a better match.
