Can anyone please tell me where i can find window crank replacements because some idiot lost the only one i had that i used to open and close my windows

i have been searching and searching and searching but i have't found ****

 

what do you need..
I may have one...do you need just the crank?

 

if you need just the handle they sell replacements at pep boys, auto zone, and o reiley... they come in a red package and i think the brand is called HELP!... or something like that
