The big difference that I notice is the knobs (and outer large dials). I think the pink one is newer, the knobs look like those on the 56-57 models, and the two tone stove looks like the knobs on the earlier to mid 50s models. The two tone is really cool! Jason, there have been a couple of them locally (in the Balto-Wash area) for not much money recently... so they are out there and available if you are interested!
