Zenith 12" Porthole

[Radiotronman]

Just picked up this zenith porthole, model G2745-OX. It has the metal coned 12" 12UP4. It uses chassis 27F20. It looks lik the schematic glued in the lower inside part of the cabinet, has a second schematic glued on top of another one. I guess zenith made changes. I'm trying to determine if it's a 1948 or 1949 set. It came with its knobs, I just left them on s bag on top for now. After I finish my 1951 philco 16", I will move in to this set next. I love the flip open doors and prismatic viewing dials on the 1949 portholes and have been searching for a console. It's wierd this model is not listed in the sand index, only the chassis? The CRT tests weak, but I think after a little cooking it will be viewable. This seller also had a extra set of knobs that I need for my zenith 29t926 I've been working on!
