Marvin is the only lettering I see on the crank. I also need the arm linkage that allows the window to crank in & out

Hello,

We would be happy to help but need to see a photo with the window open and the screen removed so that the arms that operate the widnow sash are fully visible. Thank you!

Great, take a look at our 39-031 and 39-032 EntryGard operators and see how the dimensions compare to your original hardware. Thanks for posting!
