Question about vintage Spinnaker GSD regulator

[Alexan]

Hi,
I have small collection of vintage regulators,recently I purchased Italian made Spinnaker in very good condition.
It is very interesting piece of engineering. Since all my regulators are in perfect working order, I try to service this
one too,small problem with second stage "cup nut" which secure LP hose swivel and act as switch for left or right
demand valve. I suspect that decal hides some screws or nut.
Anyone familiar with this regulator?
Attached photo of the partly dismantled demand valve.

Cheers
Alex

I have one that I've used since the 80's. Easiest breathing regulator I ever tried. was a world record holder in the eighties.
