Miami Window Corp cranks

A quick learner from Pensacola FL says:
April 5, 2023
The awning windows are installed in a home constructed in 1955. There are no patent or part numbers visible. The crank base is 6" tall, 1 3/4" deep at the base, and 1 " wide. The crank handle is 4 3/4" long. Looking to replace some missing units and need screws for others.

Hello,

We've seen this Miami box operator in the past and we do not believe that an exact replacement is still available. Our best recommendation would be the 39-054 mentioned in another customer's thread here with a similar assembly to the one in your photos.

Take a look and see if you think that this might work for your repair but keep in mind that, unfortunately, the left-handed version of this operator was discontinued and is no longer available. Thanks for posting.
