Single Arm Window Crank

Need replacement for handle and crank mechanism (arms are ok). Can you help me identify what parts I need? These are the photos I have now (I am not at the house at the moment, and won't be there for weeks). Thank you!Luis

Hi, We have very old casement windows and the handles are starting to break off. Inside the handle, it says 45054. Do I need to replace the entire mechanism? It looks like this one is more than just the handle. What do you recommend? Eva

Looking to see if i need to replace the whole assembly or just the operator body cover. If I need to replace the whole assembly, which one would fit this window?
