Thank you so much Jon, I'm going to take a long look at my abilities. It is getting as I said way to difficult to find a reasonably good model "B" core. the three that I have I think will be it. I don't know what to do regarding the power pump piston springs. As you know they are about 2 1/2 times the length of a ball point pen spring and slightly larger in diameter. I have been unsuccessful in finding them. I have a Stromberg Carlson gram meter that I used when I was with AT&T for setting switches. I have no idea what the grams or Hg is supposed to be. As many parts for these old "B's it's getting too difficult to find rare parts. It is difficult to stop doing something that I had somewhat of a talent for. If it was a Model "A" I can find anything. Rats! Doc.
