I'm conjecturing here, but the regulator first appears in the 1965 USD catalog. It is priced in between the DW Mistral and the DA Aqua Master. The Royal Master already debuted in 1964, and it was already balanced. I wonder if it simply didn't fill a role for them. For slightly less, you could get a DW Mistral, with a record for reliability and ease of service. For slightly more, you could get a DAAM or RM, and the RM was a balanced two stage regulator. Maybe the juice was not worth the squeeze?
No other American manufacturer made a balanced single stage to my knowledge. Is it more difficult to design or less desirable for customers?
Either way, if we could figure out how to solve the problem then I am willing to support it with my money and time. Is anyone interested in resurrecting the only non-functional USD double hose besides me?
Also, Herman if you can post or email the Royal Mistral schematics and stuff to me, then I will hang it on the site permanently for everyone to use.
