Jaeger-LeCoultre Navigator's Mark 11/XI Broad Arrow 6B/346 - History

Hi, I'm currently selling on ebay a c1948 Jaeger-LeCoultre Navigator's Mark 11/XI Broad Arrow 6B/346 that I've inherited. I'm trying to find out more about it's history. I believe it is a RAF Model:

RAF model with: Dial: 2nd Generation "Broad arrow"
Case back: RAF 6B/346
B/97 Hand variant: "Pointed Hour"
The watch back is marked 6B/346 2900/48 B/97
The movement serial number is 595159
The images in the link below.
However, I'm trying to find out any history of its user/squadron of the RAF. I'm not sure if anyone has every tried to find out such information but any pointers would be appreciated.


Thanks
Simon

Please note - I am not selling the watch on OmegaForums. I'm trying to get help on the history of the watch. Thanks. Simon
