window cranks for Miami window Corp window

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!
