So, this is just an entry in the war diary of the 55th (Suffolk Yeomanry) Anti-Tank Regiment, who were the first to receive Archers, in November 1944. In that context, on Nov 7, the WD has the following: "Colonel King and Major Zeigler brought questionnaire on 17-pounder Valentine equipments and discussed with CO equipments and training" Now that I think about it, I think I know the questionnaire - at the end of the year, a report was published about the opinions of users about self-propelled guns (for both field artillery and anti-tank), with opinions from many regiments. What I'm wondering, though - is were these fellows from the Royal Artillery or from 21st Army Group? Is "Zeigler" a rare enough name that it might be possible to determine? I have no other information on these two.
