HPA air fitting question???

Here is what I have going on man I am so tired of looking for this fitting I am beginning to think it does not exist. I bought a Luxfer tank from R&L then I talk to the guy who fills tanks in my area and he says he can not fill the DIN 300 valve that I have OK so I ordered the fireman tank adapter for Airhog the shop that fills is setup for the CGA 347 or fireman valve setup OK so I ordered the fireman tank adapter that should solve the problem. The adapter has the male DIN 300 thread to fit in the bottle and has the male CGA 347 thread.

I want to get another bottle so I planned to buy a SCBA bottle here is the million dollar question if I do I won't be able to use my fill station because I can't find a female DIN 300 fitting I could screw my fill station in to convert it to the CGA 347 or fireman bottle which mean I need a second fill station. I was hoping to just make up and adapter but I guess it does not exist or at least non of my searches on ebay or the net showed one.

My next thought was to change all the fittings out to the CGA 347 but the bottle I have has a different thread and I don't believe they make that fitting either. I am not sure if anyone is following this but man this sucks. I now know more about these fittings than I ever wanted to know.

If anyone knows of a female DIN 300 fitting let me know it does not matter if the other end is a pipe thread I can make that work.

Thanks Mike
 
So today I finally got the fireman adapter so the paintball guy could fill my tank so I rushed it over through holiday traffic the guy was not there but they said he was coming back so I left my tank with the new $63 fitting. I get home and he calls a couple hours after I drop it off to tell me he can't fill my tank. He says it is a scuba tank and he does not fill scuba tanks. At this point I am getting pretty pissed I bought this special fitting just so he could fill my tank. After I hang up I called a couple scuba shops and the second one I called says he can fill tanks to 4500 PSI dumb me I should have checked around better a few weeks ago when all this started but I had taken the paintball guys word that he was the only one in the area that filled tanks to 4500 PSI. I rushed over and picked the tank up then rushed it to the scuba shop and he filled it for me the best he could in the 45 minutes he had to fill it. I ended up with about 4000 PSI because we ran out of time. So now I have a $63 fitting I don't need and I could have been shooting my gun a week ago.

I spent most of today designing a tank holder fill station and I plan to cut it tomorrow. I will post pictures when I get it built. It is a carrying box of sorts that holds the bottle secure and also the gun while filling it has a shelf and a drawer with 3 compartments. It will have a spot for my magazines and pellet tins.
