Hi Gents, I remember in the early 80s, when I was collecting the WW2 badges, 1st CanPara and 8th Recce could be found for a decent price, all the others war-time badges were easy to find for between $5 to $10, the most expensive was Calgary Tank -+ $50. The "Holy Grails" were an original Garrison Batt. and Prince Rupert often talked about but seldom seen.
If you were a "serious" collector you went for the 1920-1936 badges. Like the ones mentioned by Bill, I remember the 4e Chasseurs Canadiens and the 13th Scottish Light Dragoons were very much sought after, in the Montreal shows.
BTW, Congratulations Jim for the great finds and to give you a "taste" of the Weyburn Regiment's badge, a nice photo of Major Claude Orme,DSO, company commander with the SSR at Dieppe when he was with the Weyburn's pre-war time.
Jo
