VERY nice radio!
I have a 1923 Stromberg Carlson that uses the same Neutrodyne architecture as that Atwater Kent, but instead of arranging the 3 tubes together on an island, they are distributed with one near each of the big tuning capacitors, and the whole thing is encased in a heavy mahogany box. The big tuning dials run across the front of the box. I like the exposed look of that Atwater Kent. Gives it higher "gearhead appeal", but originally the SC with the wooden case and bronze/brass fittings was probably a more expensive item. The one I have is in truly excellent condition: even the paper labels are almost undamaged, even if they look old. I'd be happy if most of the seventies gear I find was in as good a shape when found! [Although the tubes were replaced at some time, and alas are no longer the original '20s vintage ones.]
Would LOVE to get that AK (
hey, there's a coincidence! 
) but I'm sure with such a super-cool look to it, it wouldn't be cheap!
