Need new crank for my window

A landlord from Saint Paul, MN says:
Hi and hope this finds you well! Unfortunately the window needing a part has no identifying names on it so I don't know the brand. On the arm it does have some numbers written out- 3C 25 and 030303. Also on the section that has the crank mechanism there is a stamp with either 80 or 08 pending how you view it and also 2028 written on the mechanism. Hopefully my photos are clear enough to make those numbers out but if there's anything I should check on let me know. Thanks!

Hello, Aaron. I don't believe your exact operator is made anymore, but the design is similar to our 39-399 . We also sell the 39-541 guide at the end of the arm, if you needed that, as well.

Please note that this is an educated guess. The design of your operator base is still a little different compared to ours, so I can't be sure if our newer part will fit on the sill the same way. Look it over and see what you think.
