Found a thread I'd been looking for, I couldn't remember who'd posted that they'd been a recruit at St George's Barracks, Sutton Coalfield when the R Warks Regt joined the Fusilier Brigade - it was forum member BILL DUGGAN".
I was wondering if whoever had posted was actually in the R Warks, but Bill Duggan was in the Lancashire Fusiliers so probably doesn't have knowledge of which R Warks collar badges were worn.
