Hello, thank you for posting,

At first sight, your operator resembles the 39-453 or the 39-312, but I cannot confirm with the operator still installed. Take a look at the overall style and dimensions to see how it compares. Pay close attention to the guides on the end of the arms. Let me know what you think!
