I've been researching this one for a while and 1938 Ambassador is the best I can come up with. I'm hoping you all agree with my logic. The movement is the 15 jewel AN10 (4 adjustments) serial number 402013 and a crescent moon date symbol. The case is the hinged type matching others identified as 1934 and later Ambassadors in the database. However, the case serial numbers for those in the database are as follows: 1934 - 408674 - 1935 - 5050387 - 1935 - 5061224. This one's case has serial number 335827, which looks to be earlier than those above. With the crescent moon symbol and the earlier serial number I thought it may be 1928. The problem is that the late 1920's Ambassadors don't look anything like this. This style start showing up around 1934, so that's where the 1938 assumption comes from.
The movement certainbly is 1928.
1938 movements didn'y have a serial number. Looks like a movement swap but the case is certainly that of an ambassador. So the ID is correct as long as the non-original movement is noted the ID is good. Just ned to narrow downw when the case was released. Lets go with 1933 based on Fifth Avenues theory of the case serial number starting with the year of manufacture.

Excellent confirmation that the movement database is working on some level.

Thanks for the info!
Another point of interest on the movement. It is marked "FOUR 4 ADJ". The other Ambassador movements of this style in the database are marked "ADJUSTED". This may be an indication of an older movement, but I'm not sure.
Based on this discussion, should I change the name to 1933 Ambassador or just remove it from the database? I would hate for anyone to be misled.
