I have a new articulating endoscope, I suspect, my original guess of the some of the parts is wrong. I believe I am looking at the tank inside.


I believe this the check valve for over filing. The openings on the side might be items that close the valve.



The top of the tank



That has to be the gas in the tank


More gas and possible the overfill going down




I have no idea what is this


Inside that thing
