Jalousie Operator

I can't find any name/number/marks on this assembly to identify it, I'm hoping you can help me replace this because the retainer threads have been stripped out.

Measurements:
5-1/4" top to bottom (all measurements approx. hole center to hole center)
1-1/8" between the bottom two screw holes
2" - operator arm between retainer pin and link rivet
2-1/4" between operator rivet and link end screw hole

Crank is on left side of assembly. See photos for more info.
Any ideas?

Thanks Dave - I' fairly certain that won't work. I have a similar crank that I purchased on an auction site, with the 2-11/16" linkage, but it won't close the window properly, the linkage is too long.

I was hoping you'd confirm my guess of the Keller 39-061, which seems to be closer to the dimensions of my broken unit. Is there any reason I shouldn't use that operator on my window? Thanks for your help!

The business end of the window linkage has a bushing for a smaller than 1/4" screw, which should pass easily through the hole in the operator arm. But, I'll hedge my bets and order the shoulder screw and bushing just to be sure. Thanks again for your help! My wife wants me to replace the entire window over a $20 part. :-)
