Wright model 7701 hand crank

Thanks for reaching out! Your operator reminds me of the 39-028 which has been updated to the 39-028E. Keep in mind, if you are looking to replace both sides of this operator, I would recommend replacing your existing hardware with the 39-028E. The opposite for the older version isn't available however the opposite for the updated version is part 39-027E. Look over the dimensions and the design of the parts, see what you think.

The compatible crank handle is part 39-114L for both operators.

Here are the dimensions for part 39-028:
