[R-390] Cosmos Dis-assembly

[wa3frp at aol.com]

Hi Roy,
Yes, my Cosmos PTO did have a schrader valve.  In my case, it can be seen at the back of the Cosmos 
once the outer case has been removed. I assumed that they were all made that way. I'm thinking that I will 
try to repressurize the unit if I can find a source of dry nitrogen in the area.  My first thought is to approach 
the Chemistry Department of a local University.
