"The good news is I have 3 of these."
Great find, Doug, there are (were) at least 3 German makers that I know of (Telefunken, Valvo, Siemens) and they all command very high prices. A very careful description of the innards, compared to your Philips, posted on Ampage should do it --if you can't post a picture. Color, shape, height of the plates, shape of getter, shape of the little glass nub on top (if there is a diamond-mark on the bottom :Telefunken).
