Not a Sherwood?

[JamesBon92007]

I'm posting a picture of a first stage on a reg set (eBay) that says it's a Sherwood. The second stages say "4000" and "3100." The first stage has the HP port in the top section, just under the yoke. There are 3 or 4 LP ports at the bottom of the cylinder section. There are holes in the cylinder for a spanner wrench so this obviously is not a "positive pressure" first stage. Is this even a Sherwood first stage?





Thanks

It looks sherwood.

Google sherwood SRB3100 manual.

I have all the available manuals open on Frogkick but the 3100 is not one of them, however I just looked in my owner's manual and there is a picture of that first stage! Thanks! I thought I saw it somewhere but needed a kick in the butt to find it.

As far as parts go it looks like this one doesn't have the "flow control element" on the piston so that might eliminate the need to replace the piston. About all that's left is the two O-Rings, the seat, and the inlet filter. I have a Magnum and apparently the piston got clogged and no bubbles were coming out and the IP was only 100. I'm still working on it.
