What confuses me is the back case serial number starts with a C, i cannot find any Bulova records showing the letter C used. I found the 5AB listed inside as the movement, I used https://www.watchophilia.com/general-information/bulova-movements/ to determine the movement was used between 1936 to 1949.
The inside of the case has cursive writing it looks like 5-10-47 I think. also has 10/g/3
The only thig I been able to find out was the movement code, the Back case serial number I could not find since there are no "C" serial numbers, you list only L,M,N,P,T,A,B.
It was my mom's how might have gotten it from her mom.
Thanks for any help in identifying it.
