hi all, i have recently bought a gillette aristocrat adjustable (for those who don't know it's exactly the same as the slim adjustable but gold plated) it is in a perfect condition, the plating is perfect, the TTW mechanism is perfect with quarter turn and all, also the adjustment ring is perfect and clicks fine, the problem is that the plate itself won't move, it's stuck and moves under some force, also what I notice is that it is always stuck on the most aggressive settings even if i try to push the plate downwards then close the TTO mechanism it comes back to the most aggressive settings again? I have soaked it in hot water with dish soap, obviously went at it with a brush and dish soap, put mineral oil in it couple of times and let soak over night, boiled it, all with no luck of actually getting the mechanism to work, I have another TTO adjustable from Gillette (super adjustable) and when on 1 the plate moves so freely with just the touch of my finger?! it is in an overall perfect condition so I don't really know what is wrong with it. If you could help I'd be very thankful.
