Here's a closeup of the dial on my 80B:
   
You'll notice that the bezel is brass, instead of the usual bakelite variety marked "PHILCO JR."  It looks like the one used on models 51, 52 and a few others.  Every Junior I've ever seen has the bakelite bezel.  So how do you suppose it got here?  Little-known variant, factory error, or swapped by a repairman?

 It may be original, the early Philco model 60s came with a brass escutcheon, those were from 1933, so a model 80 having one isn't really improbable. Philco was known for using up leftover parts or using whatever they happened to have on hand when they transitioned from old to new models or between production runs.

It is possible for the reasons Arran mentioned. However I remain skeptical on this particular one. Notice how the speaker screws have been overtightened to the point that the screw heads have been pulled into the veneer? Someone's had their ham-handed mitts on this poor thing, and did it no favors by doing that. The same person could very well have added that 51/52/early 60 and 38 escutcheon to a cabinet that may have had no escutcheon when they acquired it.

You think that's ham-handed, you should have seen the way they connected the replacement electrolytics!    I had one eyeball on the schematic the whole time I was overhauling the chassis.  By the way, it sounds great now, and I implemented a couple of your performance tweaks as well.  Making the cabinet look new again with the damage you saw (and then some) is beyond my woodworking skills, so I took the "do no harm" approach and just cleaned it up and applied Restor-a-Finish.  Here it is:

  Looks great to me, Paul. Nice job; and the best thing is that you now have it working well as well as looking good. Congratulations, I hope you have many hours of fun listening to it.
