Left and right window operators and cranks

Question

These Marvin windows are about 33 years old. The window operators no longer crank the windows open & shut.

One has a number 30842R, the other is 30843L, I assume for Right and Left. The photo has the measurements and part numbers written on the paper.

Hello, thank you for posting,

Your operators resemble an older version of the 39-035 and 39-036. Please review the style and dimensions to confirm a good fit. For a new handle and cover, please review the 39-114L and 39-107. Let us know if you have any additional questions.
