It is a Truth brand, and the # I believe identifies it is 30744 although the following #'s were also on there, 40574 and 45108. The long arm is 9.5" in length. The crank to open'close is in the middle.
Do you have a replacement for this?
Sincerely,
Sheila

We believe we may have a replacement for you. Please take a look at our 39-216 window crank. Carefully compare your measurements to ours and let us know if this could work for you.
