casement handle 3/8" bore hole

A quick learner says:
Hi. Would you please help me find a replacement for the handle in these photos. The bore hole is 3/8". I purchased the folding crank handles 11/32" but they were too tall for the window frame, I completely got it wrong.

I'm a little confused. You say the bore hole on your existing operator is 3/8", however you say you purchased the 39-205 folding handle which has a bore hole of 11/32". How did you install this handle onto your operator?

We carry a few handles with a 3/8" spline, though none are folding. Our 39-108 "T" handle may work, though there is a chance that the "T" might hit the window sill. You could also consider using the 39-422 extension that get the handle away from the sill.
