Replacement handle/operator cover

Hi!

Looking for replacement handles in black for this operator along with what I presume is a black cover for the operator. Window brand is jeld wen wood fir wood interior, aluminum exterior. It was purchased 1 year ago from a Jeld Wen distributor but I lost the box of handles and such after the installation. There are no numbers on the existing part that was photographed.

Thanks for your help!!!
