right handed cranks and handle

Thanks for your post! You have two different operators shown here. The operator is the first set of photos can be replaced with the 39-172 Truth Hardware Dyad Operator; the one in the last photo reminds me of the 39-388 Split-Arm Operator.

To confirm if these are the correct replacement, carefully look over each of their specifications and compare them.

Both operators are compatible with the same handles and sash brackets. I've tagged the compatible accessories below this thread, along with the opposite version of both operators.
