I had to ask wifey... it looks like the same site you got the photo from:
http://www.automaticwasher.org/cgi-bin/TD/TD-DISCUSS-O-MAT.cgiThe stove sites I frequent are specific to the Chambers brand... They would think this is cool... but I don't know that they'd have much info.
I can tell you with Chambers stuff:
* condition matters. Lots of these are full of grease, mouse poo, etc. Getting it looking good can be a bit of work.
* location matters. There were distribution points in the US where they are plentiful and cheap. Elsewhere they can be much more.
* color matters. White goes a lot cheaper than other colors
* professionally restored appliances cost a huge amount, but that doesn't mean they are worth a huge amount. It just takes lots of labor and you're paying someone to do it.
* I have 3 Chambers. The average I paid for them was $100 each. These were thought to be one of the "Cadillac" brands. Mine cost $360 new. If you plug that into an inflation calculator for 1951 you get about $3400 in today's dollars -- selling for $100-500.
* if it has any original paperwork or if it came with pots, pans, lifters, broiler pans, etc... Having those makes a difference.
* if it's been stored anywhere where it is exposed to moisture... that can be death. The first problem is rust. The second is that moisture may ruin the insulation. (Chambers uses rock wool insulation ... it does not like to get wet.)
