Looking for replacement window cranks VE Andersen Oliver windows

A home owner from Florida says:
Need replacement cranks for older aluminum BE Anderson louver windows. I believe replacement would be 39-259 or 39-258 but unsure how to identify right or left handed

Thanks for any help you can offer

Thanks for writing in. If this window is a VE Andersen, then our 39-258 and 39-259 are likely candidates. But go over the dimensions listed on the product pages to be certain. Let me know what you find!
