Unfortunately, this old Andersen operator has been discontinued and is no longer available. We don't have a direct replacement, but you could consider our 39-365 and 39-366 operators as a possibility. You would also need a new track to go with it. I recommend something like our 39-504 or 39-512 . I can't be certain this will work, and it will take some adaptation no matter what, but see what you think.
