Im not familiar with the interior color the 57 GE but I can tell you I have both 55 and 56 GE 2 doors. The interior of the 55 FF compartment is yellow and the freezer blue. The 56 which has rounded corners and handles exactly like the one above is blue in both compartments. 56 was also the first year for the magnetic door latch. 57 had the new square corner cabinet which went along with the new straight line design ranges. Maybe the the lower priced fridge models retained the rounded corner cabinet beyond 56? I also have a 58 2 door. Both compartments are blue.
It could be either '56 or '57; maybe a late 1956 model. All of the features matches the LM-11N, except for the interior color. They did continue to use this cabinet in 1957 for the LB-12P, but it lacked the foot pedal feature. So again, could be a late model-year offering as GE was tooling up for 1957. Only way to know for sure would be to know the model number.
It's my understanding that the rounded corners did continue on lesser models into 1957 and maybe even '58. This threw me off when I first started paying attention to GE Combinations. I didn't realize that some of the dated looking single door models for '57 were actually Combinations, which means they had a true zero degree freezer just like the TOL "straight line" design two-door Combinations (but smaller capacity and no door shelves), and yes, they were pink inside.
It took GE a little longer to square off the corners on lesser models. Pat Coffey has a pink single door Combination with pink interior, but per the linked thread it's a 1956, so who knows what's really what with GE's interiors relative the fridge model and year.
I am now FINALLY a vintage major appliance owner I saw this on DC Craigslist right before Xmas and when I found out it was only 6 blocks away from me and only $50 I decided it was to cool to pass up........PAT COFFEY
Although it's not as pristine, there are more photos - and it's $200. Located in Erie, PA. According to the ID badge, it's a LM-11P, which would make this one a 1957 model.
Interesting how on both fridges the crisper drawer on the right is tilted.
The white fridge isn't worth $200. It would clean up to look decent with a lot of elbow grease, but it needs parts and isn't the freezer door supposed to have some kind of gasket to make a positive seal? I don't think they called them Combinations unless they had a true zero degree freezer.
