Looking for info on Seibe Neptune regs

[Coztick]

I bought these with a bunch other gear the other day and couldn't find much on them.
I will try to get pictures up but was looking for opinions from the experts.
They appear to have been in a closet for 40 yrs after some light use.
I couldn't find a reference to them on VDH for rebuild parts but would like to use them for a travel set.
Thanks for any help.

SIEBE GORMAN

Long-standing British diving equipment company "Siebe-Gorman" became "Siebe plc" in 1972. The company moved to Cwmbran in Wales in 1975 and concentrated on firefighter's breathing equipment. Hence I would expect the "demand valve" (UK terminology of the time = US English regulator) above to have been made between 1972 and 1975. Predecessor company Siebe-Gorman made two single-hose demand valve models, the Mercury and the Apollo. Its factory in Greater London was known as the "Neptune Works" (below).

Thanks Mr Wilson, my reg set looks the same except mine have a chrome finished faceplate and 1st.

I'm thinking maybe loose the brass manifold and use it for my right side
In sidemount. I already have a mr 12 for the left side.
Looking to hear from someone with personal experience with these.

I'm wondering if anyone has gotten grief over their 70's regs from dive ops or instructors.
I would certainly replace the hoses and clean/test them. I'm guessing parts are non-existent so we will see if they work.
A side by side with my Apeks should be interesting...
Just a few thoughts and a thread bump.

Have a great deal of information on the regulators produced by "Siebe Gorman" including drawings.Your unit in "Black Chrome" is a great collectors item and a good find.

Thank you sir, looks like they will go on display as both seconds freeflow a little and parts seem unlikely.
I suppose I will stick with function over fashion and pack the DSTs.
I will message you later from home regarding info. thanks
