Once I am over my hatred of online photo hosting services I may once again add pictures to forums. As it is I've lost countless hours and links to my photos thanks to photobucket. Five of my HW SH regulators have serial numbers. Four are on the cover and one (Scubair B) stamped into the chrome. Those without apparent serial numbers include My Gold label 300, my Airflo and a Scubair J. The J has the previous owners name, year it was purchased, and the dive shop where it was purchased stenciled inside the second stage. Here are my complete regs with serial numbers.
Scubair Diaphragm 1st stage Upstream red label blue bodied 2nd 10301
Scuba Star 1st stage Upstream blue label 2nd 13459
Scubair Diaphragm 1st stage Upstream red label 2nd 17272
