WW2 Army Pay book & Release book, Gunner 136th heavy A.A R.Artillery.

John Charles Frederick WATSON was a 37-year-old painter and decorator who enlisted on 12 June 1941 at the start of his service, was passed A1 fit, and went through the standard inoculation course that month. He served right through the war. His medical category was downgraded from A to B7 in July 1943, which meant he was no longer fit for full active service overseas, very likely why he ended up in a home-based unit. The final B7 category and the discharge examination at Ipswich on 6 October 1945 suggest he was released from service that autumn, several months after VE Day.
Given the context of the previous conversation about the 136th Heavy Anti-Aircraft Regiment, his service profile fits perfectly with that unit’s history: a slightly older man, medically downgraded mid-war, serving in UK home air defence right through the Baby Blitz, D-Day cover, and the V-1 campaign. The Ipswich discharge location is also consistent — that’s East Anglia, the heart of the Diver Box where 136th HAA was deployed in late 1944.
