Well Kirk it's just about done. I was wrong it is a 2 band set (BC +Pol). After working on it for a couple of days (since Monday) it's working picking up many station across the BCB. The Police sensitivity stinks but there is no adjusts for it so it is what what it is. Did pickup CHU' time signal @ 3.3mc or so but was weak.
It kinda follows your schematic but the choke in the p/s was open so I changed the circuit to a cathode bias from it's original grid bias. So the p/s is pretty different. Spkr was trashed so removed the output transformer (still good) and added a 6" pm spkr in it's place.
Volume isn't quite where I'd like it. It's not bad but should be just a bit louder. Should test the 43 to see if it's weak and maybe optimize a resistor in the det circuit.

figure out what all those squiggly meant.

Now I think I've got!
