There are no Canadian Snider boxes, what there is are British boxes sent to Canada, there would be no difference in any way for the original 1860s boxes. What is shown is surely one of these boxes refilled. It would be a nice box to have here as mostly if not almost entirely are the origin shipped boxes, sometime nice condition, sometimes not.
There are a fair number of them over here and the realistic value for a decent one is $200.00 Canadian The price I just saw is rather excessive
as they don't seem to sell for more, from my experience. The next mark of Snider box which is larger is quite rare how ever and Martini boxes or Boer War era 303 boxes seldom show up compared to the regular Snider boxes. My Snider box was repurposed to hold 303 gallery rounds pre ww1.
My thoughts at any rate.
