Vintage Double Hose

My newly finished doubles project.
Sportsways SJ2 manifold
Orange County 38's (1800 psi WP)
USD DA Aquamaster with Cyclone Balanced First Stage

Very Nice! Now if only I could find a set of 38s with 3/4" valve threads. My search continues! Mark

Looks like another "Mike Nelson" clone for Sea Hunt. Tanks are spoken for.

Da pride of Soviet people production es is Podwodnik AVM-1. Es superior to capitalist device.
My latest project and some of you have these dinguses. More to follow.
Interesting duckbill and diaphragm. I have already gotten an "new" 1st stage and main 2nd stage diaphragm from the Ukraine.

In reality, the AVM-1 is a modified single stage. The so called first stage diaphragm is a high pressure activation device hookup that allows air to flow to the second stage. It is triggered (opened up) only when tank pressure hits the diaphragm, which is the reverse of say a Mistral. Internally its "1st" stage has two up stream seats that are adjustable for various tank pressures. The outer pressure relief valve is supposed to be adjusted to 9kp if I remember, and is easily adjusted using a set ring to secure it. The main body also has a LP port for additional equipment such as either another second stage reg or possibly a power inflator or other kind of equipment of some kind. I am pointing to the adjustment valve in the picture and the LP port is the opposite chrome looking port cover.
There are no one-way valves in the mouthpiece and is reminiscent of a CG-45 and other early La Spirotechnique regulators and allows the hoses to get flooded which could cause the untrained DHer to have possible problems if he or she does not know how to clear a flooded hose in its entirety.
Should be fun and I am awaiting a din adapter that fits better than the one I have from Russia. Breaths surprisingly well, but we'll see how it does in the pool when totally done. All in all, it is a very well made and robust reg.

Just dove newly rebuilt 1020 "Jet Air" this weekend in the Red Sea. Serial number is 3810. I'm guessing it is from around 1962. That said, I used a heavy yoke replacement due to the 3442 130 cu. ft. tank I was using, along with a Banjo fitting and the thing worked great. Obviously a little effort with regards to breathing effort initially but not to bad. Once the TP got down to below 3k it purred like a kitten. I of course will retain its original yoke. The reg. was obviously a fresh water reg. and was in excellent condition for re-build. It is nestled in its original form along with some other projects in the picture below.
New everything including sticker.
Not a great pic of the serial number, but its there!

This is a very early Voit "Trieste" serial number 00494 with single HP port on the body as well as the all metal yoke screw. I have the original box and the hoses and mouth piece, though grimy with age, are still flexible.

I could not find something which resulted in my digging through numerous boxes, my stuff from my 66 to 72 era, either the stuff or similar to or same as:



Sorry, putting in new carpets and baseboards.

Nice Kinugawa mask Nemrod!

Ok so here is a Voit 50 Blue Can that had all original hoses and mouthpiece on it. Opened it up and look what I found. Polaris 50 guts. Greg the Lung had not seen this one? Any one else or did the boys on the line run out of Voit 50 fathom guts on the assembly line? Either way I plan on leaving the original paint hoses and mouthpiece as they are in great shape. think I will make this one an everyday diver till the paint flakes off!

My collection so far. Not pictured are two other regs that are in the process of getting rebuilt.

Me like!!! Nice set of doubles too!

A work in progress. Refinished the HP seat and got it to seal and breath well! Super excited to get the voit hoses and mouthpiece on it to finish it up.
