AVION Travel Trailers

I have a 1969 25' Avion. I have worked through the stove top, fridge, air, water leaks and have it running pretty nice. Now, looking at the possibility of hot water. When I look at the pilot assembly and control switch, I am missing the top knob to turn off/ on and pilot. Anyone know where I can get...

yes. I was able to get to it under the bed. Just tightened down the 4 screws on top and it stopped leaking!

Can you guys take a look at this picture? Is this a pressure regulator? It is leaking and dripping from each corner when city water is hooked up. Also appears to be the 7/16' size copper lines.

1969 25' Avion. Thanks
