OK, well, so after staring at the sch again, I realized the problem had to be the #12/12A padder.
I put a scope on the oscilaltor: it worked fine on the SW band but switched to 11.8MHz at the BC upper part, while quickly failing to oscillate soon after starting moving toward the lower end of the scale.

So, I was able to restore the oscillation by adjusting #12 padder (the nut), which was somehow well out of range, and then I got reception on the BC, and then I was able to align it.
Now I have nice reception on both BC and SW.

The dial look sad: it was in bad shape in the first place; I removed the bulge in the middle, so the pointer could move freely. As I said before, if ever found, the dial will be replaced.

Now I have to go to cleaning the cabinet.

PS. And, yes, the speaker works. I cannot explain what I saw and the behavior of the Field coil resistance, but the speaker behaves quite normal, sound-wise. I'll take that for now.
