I need to replace several casement window operators. They are from a house built in the last 60's. The crank handles have Malta on them. Otherwise, there are no distinguishing marks on the window frames or cranks. The bottom of the cranks have a LH or RH depending on whether they are left or right cranks. You should be able to see the measurements based on the pictures.
