Window crank cover and folding handle

We just purchased a house that has casement windows and we are missing two cranks and have one missing cover and three cracked covers. The cranks say "Truth" on them. I see replacement covers on your site, however they don't appears to be the same shape and also have a slit in the cover. I attached photos of the covers we have and are trying to replace. Also, I am also looking to replace the cranks with folding handles as I cannot close our blinds with the handles attached. Can you help with both? Which parts do we need? Thanks for your help!
