22ème St John's Battalion C.E.F

[Chipper]

Hi there,

I have a question for you all. For the 22nd Bttn, CEF cap badge: in particular the smaller E-22-A version - is there any difference between a CEF one, and a later, WW2 and beyond examples?

i.e., can they be positively identified to a time period, or like say, British Royal Artillery, was there no real way to accurately date a badges over an extended period? (at least till the crown change in the 1950's)

Any help would be much appreciated

Cheers, Tim
