Movement symbol on the inside is "49". On the outside of the case (back) "0" or the letter "o" or circles (2, one on each side) flank the "14k" mark.
I had so much difficulty trying to find a similar watch I thought I'd share it here if it'll help others. From the info I gathered on your site I was able to determine (I think) that the movement date is 1949. I looked through the ads here for '49 and a bit after and didn't find this watch. However, it looks a lot like the watch a member here has photographed along with, I believe it was.. The mens Ambassador from 1935.
I'd already listed for sale elsewhere, I'm just here to add this in case you don't have the model. It may simply be that I didn't search well enough.
