They have two gearboxes for the 850 one is a domestic one CH87295A and the other is the commercial one CH87296A. I have attached a parts list for the commercial one.
Sounds like the domestic models need the commercial version going by the drama in that review MW posted. That mate doesn't deserve you NK!
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
