Handle says stanley. Vintage 1960 jalousie operator

Spacing between the 2 mounting screw holes is 4 3/4 inches. Only 2 screw holes on outside. But when you look at inside you can see that there could have been 2 more screw holes, but casting was never drilled through. Note rivet in body is above the crank and the arm swings down. All the other ones I have seen have the rivet below the crank. Link is about 3 1/8 between centerline of holes/nubs. Handle clearly had Stanley written on it and it is 6 sided. Also note shape of body and that crank is near center. it was mounted on the lower right side of jalousie window. Stamping on link is "359" which I assume to be March 1959. Inside it says "pat appld for"
