Truth window cranks

Hello, thank you for posting,

The operator in your images resembles the 39-013 and 39-014 with a 13-1/2" arm length. Please review below to confirm a good fit! Also see the 39-114L for a compatible handle. 

Dimensions for 39-013

If the operator with the smaller arm is the same style, take a look at the 39-027E and 39-028E that has a 9-1/2" arm. If the style differs, we will need to see images of the original to move forward.
