Question Any idea?

[axxel57]

This 1st came with a Tekna 2100B 2nd, it has 2 LP Ports and one 3/8 HP Port, so it is for sure Vintage.
It is a piston 1st with a particular adjustment mechanism ( an adjustment 'disc' which is rotated up or down with a spring and metal pin below which clicks into one of the four dents) . S/N is 3568
I have no clue where to look for that, even when I think I have seen this cap before, but I don't think I have it in my collection.
Brand? Model?
Anybody here who can help?

Very interesting.
Beuchat had a similar IP adjustment system with three pins though. A plate that was threaded would be used to adjust pressure on the plate that was opposite of the pins against the spring. Perhaps and early version of this?

I don't know a three pin adjusting system from Beuchat, but from Cressi Sub for example in their Mk5 clones and still nowadays in their AC2s. I like that easy adjustment system more than the shim system of SP.

It's embarrassing, but I have simply too many Vintage Regs.............
I was somehow sure, I had worked already on that type of 1st before.......
