Here he is when in the British Army of the Rhine occupation army. He was a military warder at this time and once guarded Rudolph Hess. Not sure a stepfather qualifies as an ancestor, in fact of course he does'nt.
This Staff Sgt., in the M.P.S.C., was a great recruiting tool,FOR THE NAVY!

Fairey Battle

This is an Archer self-propelled anti-tank gun of the British XXX Corps. The Archer was, in essence, the superb 17 pdr. anti-tank gun, on the hull of the obselete Valentine Infantry Tank. This photo was taken during Operation Market-Garden, as XXX Corps was attempting their linkup  with the British 1st Airborne Division. (scanned by HOS Bandit)
