We have old Hope operators in a 1950's house. The arm measurement is 9.5" rather than 9", measured as you show in the diagram. Will yours work OK on our windows (i.e., just shorter swing-out)? The crank on ours is not centered on the base, but offset a bit. Is that also OK? The 4-1/8" screw mount mounting measurement is what I have.
