Snark 111 Nemrod by Seamless #08651
Snark 111 Nemrod by Seamless. Nemrod advertised this as a “3-stage regulator,” but the third stage is that overpressure relief valve you see at the top. The first stage is a standard spring-biased diaphragm stage (unbalanced), and the second stage is basically designed like Mistral, even having compound levers for the demand stage. The LP diaphragm is a nice, flexible one which will last as long as the regulator. The exhaust mushroom valve, which Jaybird said could be a problem, is also robust and should be in good shape even after all these years. You may need to treat it with silicone grease to revive it, but if taken care of it should also last as long as the regulator. Basically, this is a very robust regulator.
