Operator Cover and Window crank

I eyed up the old part and incorrectly ordered item number 39-155. Now that I took out the old part I see the new one won't fit. I can now see numbers stamped on the old crank: on the gear is 30844R and on the lever is 30842R and the word "TRUTH" is also stamped on the assembly. Could I return the unused, incorrect part and would you help me get the right one? Thanks much. Joel

Gentlemen, Here is a picture of the original window crank and operator cover from my small bathroom window. The gear turns back out of its proper place any time one tries to close the window by turning the crank, so I need the replacement. My problem has been that I see nothing on your website that looks the same to me. Please help me get the correct part; I've already wasted 35.78 on an incorrect purchase (item 39-155 was way off, not sure about 39-107).

Arm Stamp: 30842R
Gear Stamp: 30844R

The screw post that attaches to the handle and turns the gear in the actuator has pulled out away from the gear. I tapped it back in but the metal housing that holds it in place has spread and cracked. I have been told they are Pozzi windows; the metal arm has the following numbers stamped into them 30841L and 30842R. CAn you help me find these parts?
