Hi Folks,

I purchased these about 15 years ago from an LDS. They were used (from their rental stash).
Anyone know what model the 1st and second stages are? The 1st stage has 7 ports -- 5 LP and 2 HP.

Thanks.

Looks like Sherwood SRB5600 Maximus!

Manual

I believe it's newer, 6xxx or newer.

@dflaher check over the first stage, it should have the model number etched into the chrome, it will be SRB followed by four digits. Then the Internet is your friend. Sherwoods are my favorite.
 
Almost correct. It's a Sherwood SRB7600 (maybe D2) Maximus, the last 'Dry Air Bleed' First Stage model before they changed for the 9000er Series with Schrader Valve in 2009.
First Stage is the same as the SRB5600, but the 2nd was a bit different.
 
It is difficult to imagine a simpler and more reliable first stage, especially since they moved the bleed off of the piston.
 
I've got a very old maximus. Second stage isn't nearly as tidy looking. Still breathes great.
