What type of Subal Dome Port is this ??

Hi,

I have just picked a Subal ND20 Rig and I am trying to identify exactly what of Type 3 Dome Port I have.

Its 9cm (3 1/2") high and the diameter is just over 18cm (just over 7").

Any assistance would be appreciated.

Thanks 

Hi, it looks like a Subal 200 mm, 8 inch port.  I too got this dome port, in perfect condition as part of a Subal ND20 rig, together with its extension port.

I believe the Subal name for this port is something like the 8 or 8.25 inch dome port.

From time to time eBay sells the Canon C20 (?) camera body for next to nothing, to complete the camera-housing package. I have yet to dive with it, will have to wait until the Corvid epidemic quiets.
