I’ve had a few of these over the years, this box doesn’t have a part number on it, but looks the same as one I sold about 6 or 7 years ago, see last photo. XE-7210-A

Study the photos as where they engage in the box there are slight variations and the shafts are different in lengths, some have more curves then others.

Overall shaft length is 335mm
