Qor Pin ???

Hi Oh Wise Ones,

We're trying to identify a QUEEN'S OWN RIFLES small pin that I found in a 2nd hand store and gave to Geoff as a little birthday present, if anyone can help. Here's the description:

Small Metal Maple Leaf

White enamelled oval in center saying "Q.O.R. of CANADA"

In the center of the oval it says "83"

Beneath the oval it says "OVERSEAS BATTALION"

On back it looks like "ELLIS BROS LTD"

Thanks

Karmen

(typo finally fixed by me ... K )
