Ed, please take this in the light of well-intended advice (from someone who is admittedly a stickler for period-correct insignia) rather than criticism: if the collar badges you have are for a GAF uniform/impression I do hope that your reference to the collar badges as "RCMP" is a typo, because the Royal Canadian Mounted Police did not exist until 1 February 1920, when the Royal North West Mounted Police (which had jurisdiction only in the Canadian West (i.e. west of Ontario) was merged with the Dominion Police (which had jurisdiction in Eastern Canada.)
For that matter, until 1904 the name of the Force was "North West Mounted Police" (the honorific "Royal" not having been granted the the Force until that year.)
The correct badge from the creation of the NWMP in 1873 until after Queen Victoria's Death in early 1901 is this:
Note the distinctly shaped "Victorian Crown" at the top, and the name "North West Mounted Police".
For the very brief period of 1901 to 1904 the crown surmounting the badge was changed to the so-called "King's Crown" -
Note the quite significant change in the shape of the crown ...
From 1904 to 1920, the badge was quite similar to the one above, but the name on the scroll at the bottom changed to "Royal North West Mounted Police" -
