Sel Rex was a plating system sold by OMI. OMI are now part of Enthone-OMI, based in New haven Conn. USA. Enthone have a branch in Woking, in the UK. As I recall, Sel Rex was a gold plating system that used cyanide. I think it also used nickel to harden the gold, as well as using it as a base for the gold. Try contacting Enthone directly, or through an agent.
