[Bombphoon]

I wonder if anyone can possibly answer a long-wondered question my family and I have wondered about for years!.

On 29th January 1944, my grandmother's first love, Flight Sgt 520581Leslie 'Spike' Watson took part in an air raid on Amiens, France. He was one of eight Hawker Typhoon pilots of No. 1 Squadron who attacked the St Roch railway marshalling yards there. Unknown to them, the 9th Armoured Hohenstaufen Division were based in barracks alongside the railway with the 4th Battalion Sicherungs-Regiment 191. Watson was the last one to bomb the railway yard - and sadly he did not pull out of the dive, possibly shot down by light flak.

My question is, we know his a/c no was JP498, and his squadron lettering was 'JX' but what was the individual letter after this i.e. JX-??

Many thanks for your help,

Kind Regards

Austin
