While beginning an Aurora 88K piston replacement I removed the section/nib unit and saw this. I have yet to touch it. It looks waxy. Has anyone seen anything like this? I am hoping the retaining nut and such are there and this is not all that is holding the seals in place...
edit- It definitely seems to be wax after touching it. I also touched a razor blade to it lightly and it did nick the substance which is another reason I think it is wax. Once fully extended like this the piston knob keeps turning.
