There are no marking on the cranks. This Florida house was built in 1967.
I believe the hole is 3/8 of an inch wide but there is only one hole at top and two at bottom. I believe that the arm length is 2 and 1/2 inches. The handle came right out of the crank casing hole and I cannot get it to stay back in the hole. You have one similar but it has two holes at top not one hole. Not sure if I could use that one anyway?

Hello, thank you for posting,
Start by taking a look at the 39-193 operator along with the related hardware and videos. This operator could be the one you are looking for. Look at it on the website to see if in fact it does match up to yours in dimensions and mounting hole locations.
Let us know what you think and if you have any additional questions!
