Hello, Bart, thanks for your patience during this busy summer season. I agree that our 39-124 is similar in design, but I can't judge for you whether or not it's a match based on these photos. The only thing that can decide that is the precise size of the spline. In the case of the 39-124, it's only made to work with 5/16" operator and handle splines. You'll need to measure the original as precisely as you can to determine if it's the same size.
