I have the Promate parts list in PDF if you need it.
That's a big order Zung and winter is almost over but maybe we can start working on something. There are really only common 2 basic types out there, the old standby USD RAM/Conshelf/Titan/SEA/Legend/Mares MR12/ bunch of others and the Apeks design for which there are dozens of clones- DR/Salvo/Promate plus the Zeagles are based on them as well. The vast majority of diaphram regs that I have seen fall into those 2 types, other than some older Healthways and Dacors and even those use the same size diaphrams.
