If it's a Mk.1 in shootable condition and hasn't been touched...$1,500.00 to $2,000.00, a Mk.2 in similar condition would be similarly priced. There are many more Mk.3's around and some marked to Canadian units. These 3's would be in the $800.00 to 1,200.00 depending on condition. Mk.4's (long levers) are not as desireable for many reasons and are usually $400.00 to $600.00 as long as they haven't been cut or refinished. If it's one of the Khyber or Nepalese rifles...buyer beware. An opinion, Dave......by the way, if they can be traced to the Zulu uprising in Africa prices can be higher. Mk.4's were never issued in Canada and I believe also never used in the Zulu rebellion either.
