On the topic of the destinations various Ross rifles saw military service and application, I was just reading today about a colorful character named Morris "Two-Gun" Cohen who in 1911 bought 500 rifles for China. He was London-born and became a Kuomintang general. He reportedly was quite involved in some unstable times during the Sun Yat-sen era. Interestingly, the 500 rifles he bought in 1911 in Winnipeg, Canada were all used and reconditioned. Cohen is reported to have made a second trip to Canada in 1925 to buy more Ross rifles but the outcome of that trip is not documented. Cohen passed away in 1970. I have seen a picture of him seated with Chiang Kai-shek in his later years, so he must have been someone of some ongoing importance and influence.
