Thanks for the congrats. As to the serial numbers on the guns in Canada: In 1976, when I returned to Canada after University in Texas, I had a Griswold & Gunnison revolver I put together from a kit. The RCMP had a fit over that one. I had to go to the nearest RCMP office and register it with the promise I would stamp a serial# on it, which was required. Then I had to get a permit to 'convey' it to my parents home in N. Vancouver.
My grandfather had all the GF Ruxton books. He said we were related to Ruxton, but I don't know how. I think it comes from before his parents. His father was English. We were from Aberdeen, Scotland, so the crossover occurred in the 1700's.
