Hi, I have a couple of double hose regs I'm looking for parts / advice on please.
Reg 1 is a 3rd gen Siebe Gorman Mistral, I'm looking for a diaphragm, or a lead on where to get one made. The original is so hard I can stand a half full coffee mug on it before I get any movement. I've tried soaking it in silicone oil for a week but there has been minimal improvement.
It has been suggested using a USD diaphragm but that diaphragm has an outer diamater of 4 5/8 inches, a height of 3/8 inches and a disc diameter of 3 1/4 inches.
The original Siebe diaphragm has a diameter of 4 9/16 inches, a height of 3/4 inches and a disc diameter of 2 3/4 inches.
Reg 2 is a 1st generation La Spiotechnique Royal Mistral and I'm looking for the lever height adjustment stud, thumbwheel and lock nut - all are missing.
I've emailed Rob at the Scuba Museum - very helpful and I've ordered some parts, but the SG diaphragm is an odd one.
Thanks in advance.
