I was given these a few years back, and only just found them again when I was cleaning out a few cupboards this week. I'm pretty sure the first (with the badly worn scroll) is an RA collar badge, but the 2nd and 3rd have me a little stumped. Is the 2nd possibly from the RE? The smallest of the three, though, has me totally lost.
Difference between sapper & gunner grenade explained here. http://www.army.mod.uk/royalengineers/26401.aspx 3rd one could be Grenadier Guards grenade as worn on epaulette of Service Dress
IN WW1 Gren Gds NCOs wore a grenade above their stripes. As shown here. On left & right of photo with 'Grenadier Guards' red & white cloth shoulder titles. http://www.iwm.org.uk/collections/item/object/205072583 THE BATTLE OF THE SOMME, JULY-NOVEMBER 1916. © IWM (Q 1256)IWM Non Commercial Licence
Thanks Owen & Drew, your replies have been very helpful. I didn't think of the Fusiliers at all - now trying to figure out how that all tallies with my father's family. Most of his uncles served in WW2, but with Australian regiments I think. Or my grandparents just scored a whole heap of old badges over the years and I just inherited them, with no connection to my dad's family at all.
It was indeed used as the generic fusilier section of the two part shoulder title worn by fusilier regiments during the Great War.
