Windsor Egress hinge arm operators and accessories.

Looking for Windsor Egress hinge arm operators, their part numbers 540019 and 540020, one pair both right and left.

Also need one of the posts that screws onto the bottom of the window that the short arm of the operator slips over and clips onto. Need the one for the left window looking out, or the right window looking in. Can send picture of the same part but on the other window in necessary.

If these are available I will also need one contour cover and one crank handle.

Pictures attached, including one with ruler for scale..

I also need one of the brackets that screws onto the window for the short, hinged arm to clamp down on to. In one of the pictures of the unit in place you can see two screws in the bottom of the window frame, to the left, where the egress operator bracket, Windsor part number 540022, used to be. There is also a picture of the opposite window's egress operator bracket, Windsor part number 540021, still in place. I need the one for the left window looking out, or the right window looking in.

Thanks.
