Guess who has a birthday tomorrow and found himself a sweet birthday present?
That is currently my everyday diver. Primary and secondary. That is some really nice looking chrome.

My project today is to rebuild a 1967 Voit Trieste utilizing some secret skunk works ideas to make it breathe better than stock. I've run all metal parts through my ultrasonic cleaner and laid out all original, NOS and new parts in order of assembly. I sized all the original o-rings and found a great chart on VDH that translates Voit oring part numbers to todays oring sizes. Here goes ..... 
P.S. Also had to swap out a Titan II body for the Trieste body as the Trieste body was all buggered up inside and FUBAR. Of interest to me was the fact the Titan II 1st stage had a US divers HP seat and a .630" pin so didn't have to trim down a Conshelf pin. It is also an early model without a teflon backup retaining ring in the balance chamber, just a -.006 o-ring. Once I get it together and get the cracking pressure as low as possible I'll experiment with some venturi adjustments...

Definitely not today's reg, but just found this Draeger Secor 300 S in the bay. It was almost exclusively built for the German Military between 1975 and 1985 as far as I know, it's made of stainless steel (antimagnetic) from one block. Draeger calls it 'piston' first stage, weird technique with static IP at low tank pressure about 12psi higher than with full tank.
I'm pretty sure it never touched water.
Those military guys must have been real heroes if that adjustment is the original one from Draeger and was standard, static IP 85psi at full tank, CE 1,9 inch/h2o and pretty lousy performance at flow for nowadays standards (the dismantled first is a pretty worn DIN Secor 300 first I found in my cupboard, last photo).
Anyway, it's also pretty shiny from the front and I like it.........
