I have a question for you tiger tank aficionado's....the knob on the vent on engine hatch, was that used to adjust the height or lock it down tight or both ?

This is a quote from a book which is talking about the vent of a late Tiger 1.
"With the wading requirement dropped, the tightening lug for the forged cap was eliminated"
So I guess that lug was used for tightening the vent cap.

Thank you Vince ! I agree and will assume it would have to adjust height as it is a vent

Mark, did some more digging and found a photo of the vent with the knob missing. There was a caption under the photo which was saying that inside the vent cap was a valve that was closed using a control knob. This would normally be left closed to allow the Feifel air cleaners to provide filtered clean air to the engine or also closed during submerged operations to prevent ingress of water into the engine compartment.
So I guess that knob was used to open or close the internal valve only.
