I don't have anything else on the revolver or the owner. My initial post included information that I picked up from several internet searches. I could take some lessons from yourselves as you found more information than I ever did. I picked the revolver up at auction last year and there was no accompanying paperwork. Being a soldier myself, anything with Canadian military provenance catches my attention, so I ended up paying more than a New Service is worth based on that.
Zipperhead - Don't let any discussion here dissuade you from the pleasure of owning your Colt New Service. Purple and I just like to pick fly sh!t out of pepper at times, but basically we're on the same pages of history. We all enjoy Canadian militaria immensely and re-fighting battles.
If you are happy with the gun and the provenance, then it is worth every dollar you spent on it! I've over paid (the going rate plus) more than once for something I wanted badly because it was available and I didn't want to lose out on it. Occasionally, we all get a sweet deal others can only dream of. Sellers either over value an item or the reverse. If everyone is happy, it's a win-win. That's part of the game.
