I hope someone will be able to help you out there, I have the same model and to be honest, I wouldn't have a clue really what they are for!
I would hazard a guess that they may have had something in mind for a later model, or that model, which didn't make it off the drawing board...Maybe one of the Victa GURU's on here can provide some insight..
