LEC Carbine
There were 2200 Lee Enfield Carbines imported into Canada for the Military. This is a very nice piece. It is not cut down, and has the correct magazine. There should be a link on the front of the magazine to keep it from being lost. The markings on the Carbine are on the left side, the rifle on the right side of the butt socket. The bolt, receiver, barrel and rear sight should have serial numbers on them. If they match, you are golden. The six round magazine and forward sloping bolt handle with the flat on it are so that the rifle can be carried in a scabbard on a horse.
Some of these went to the Royal North-West Mounted Police. The picture of the butt stock below is an example. On the RNWMP Carbine, it is 3rd Squadron, D Division (Fort MacLeod to Fort Steele in southern Alberta and British Columbia.) This is an 1896 dated one. Unfortunately, Bubba took a chomp out of the forestock of my Carbine.
The unit markings 4 / CA / 264 are interesting. What makes it more valuable is the name on the ID disk. Officers were expected to provide their own kit, including firearms. The Name on the ID disk leads one to surmise that this was a private purchase.
Canadian Artillery was usually marked CFA for Canadian Field Artillery, and CGA for Canadian Garrison Artillery. I could not find a CA marking information in my reference books. The 264 is a rack number, that is this is the 264th. rifle issued to that unit. A bit of speculation here....a short rifle or Carbine makes sense in an Artillery or Cavalry unit. An officer would be mounted on a horse, so this Carbine is appropriate.
It is also important as to when the unit markings were applied. If after August 6, 1914, then the markings would indicate 4th. Battalion, Canadian Expeditionary Force (Central Ontario Battalion) which would account for the 4.
Is there a Broad Arrow or an Arrow within a C or an arrow with D^C stamped on it on the barrel or receiver? We are assuming that this piece is Canadian, but what if it was brought into the country by an Immigrant Military Officer? In checking SKENNERTON, the only reference to CA I found was for Austraulia, New South Wales, for Cadet Artillery.
The same Inspector's number A9 that is on your bolt, is on my RNWMP 1896 Carbine bolt. (A thought here---check out the RNWMP files for the name of the Officer ....they had to buy their kit the same as the Military, and a personal firearm would not have the RNWMP stamp branded into it.)
Anyways, the name gives you an interesting place to start. Markings on guns are a fascinating study, particularly on personal pieces.
A great find....good luck.
