This is why I bought the" FULL 'B' tank with accessories" advertised on CL today. The OOPs moment came when I got home-nothing interchanges except the hand torches themselves and the larger "B" is full of 100 % Acetylene. My tank is an "MC" tank and regulator an MC regulator. You'll notice in the 2nd pic that R is cast into the back housing next to an assembly pad for stamping final use code. The Web has numerous RB regulators but NO R MC regulators. Problem #2 is I now have 3 regulators and the only good one (shown) is an R O and it fits NIETHER TANK.-The 3rd regulator(an RB)-not shown- is junk but the fitting fits the B Tank .
The reason I figure this will take an old timer is that the guys at my gas supplier are clueless unless their computer screen has the answer.
SO, DO I punt? Am I back to square one and $50 lighter or what ? I'm hoping to swap diaphram/spring and rear casting to fit either the MC or B tank-Has anyone done it?
