A clamp marked Divetek
Hmm... does look a lot like a Sea Hornet MK1 but has a slightly different central IP adjuster and an early Aqualung style yoke clamp knob.
The IP on these is adjustable externally via the hex key end cap pushing on the three pins which in turn transfer force to the mainspring vs the usual shims. Should be 10BAR or 145psi.
A good idea in theory but the design trapped water around the pins often causing corrosion despite careful rinsing.
They can be overhauled with standard AS568 o-rings and the HP seat either carefully lapped or flipped, some parts are still available from ProSub in Germany.
The diaphragm MK6 or sealed 6/S was Sea Hornet's best design IMO.
I obtained a large amount of historical info from Peter Katz (Sea Hornet's Chief Engineer for many years) and am working on a short history article for SB detailing the various model's product development timelines, and importantly, the brands they custom manufactured regulators for.

Was brought to me for assessment. Seems to be a balanced piston with the 3 pins instead of shims for a

Many thanks.
As it is a Divetek, I suspect it could be a Beuchet V4.
I should have checked on the manuals I downloaded from www.frogkick.dk
Divetek seems to buy up old tooling and launch their own product.
