Hi, Apologies if this is in the wrong place. If it is, please could you direct me? I am researching a motorcycle used in a 1944, for a friend. The first part is that I can identify it formed part of the Guards armoured division - as the badge, I knew pretty well, is still visible: The rest, I'm not 100%. The background looks like a dark-blue, with a 3rd quadrant of a square, being Red. I'd therfore attribute this to artillery and 3rd battery. The H, would denote 'H Troop'? There looks to be something to the right of the H, but I can't quite make that out. H (on some websites) denotes a battery command post officer vehicle. But It could also mean troop? So there is a bit of confusion there for me. The front of the bike shows the same H and the same tac sign (blue square and red quadrant), but above it, there is also a Y and it looks like a badge shape, with a red top. I've read that the 'Y' could mean Battery survey officer vehicle. Is this likely? were surveys in NW europe conducted on motorcycle? Any thoughts? Sideline question: As this also was attached to the Guards armoured, they were made up for 5 artillery components: · 153rd (Leicestershire Yeomanry) Field Regiment, Royal Artillery 01/06/42-11/06/45 · 55th (Wessex) Field Regiment, Royal Artillery 08/06/42-11/06/45 · 21st Anti-Tank Regiment, Royal Artillery 01/06/42-29/05/45 · 75th Anti-Tank Regiment, Royal Artillery 01/06/42-11/06/45 · 94th Light Anti-Aircraft Regiment, Royal Artillery 01/06/42-11/06/45 I've been trying to find, which of those would have had a 'H' Troop - if indeed, the H means Troop! Early research on the 153rd, shows they didn't have a H troop. The research material for them online is really good. So I've ruled them out thus far. Can anyone else help point the way for this bike's attachment?
