Being as I am a big fan of the Welsh Guards
I have these.
The top one being modernish the following two have Press studs which would indicate to me that they were worn by the 3rd Bn during the N Africa/Tunis campaigns and possibly later also in Italy. The two at the bottom are the same pattern as the smaller font Press studded one, not an exact science but I think indicative of WW2 type titles??? and British made.
