need a crank handle

Hello - I am looking for a crank handle for a casement window. Color seems to be a sandstone/beige color. Window currently has crank handles but they do not fit when folded. Looking for both a Left hand and right hand. Unsure if there is supposed to be a cover for it? Looking at some pictures if I was to guess I would say a sill mount encore dyad operator? Can someone verify and get me the correct style crank and if there is a cover? The operators still appear to work well.
