Ben:
Yer darn tootin' that's sweet. 40-inch Stratoliners from that era are not all that rare; you might have to wait a bit for one to come up, but they do come up. But the 30-inch version - now that's a different kettle of wombats. Nice find. Nice find.
The one thing I've always wondered about on the 30-inch version was the provision for three small burners and one large one. Given that GE lavished every other feature of the 40-inch version (except the two ovens, of course) on the smaller model, it seems strange that they wouldn't provide two large and two small burners.
Anyway, as ever, your collection seems to be the one that has all the goodies I dream of!
