Lyman Alaskan Scope

I have a Lyman Alaskan 2 1/2 X scope with fine cross hairs & a target dot that I took off an 03 A4 clone I purchased here in Canada & have since used an M84 scope in its place. Talking to a dealer a couple of days ago & he mentioned that it may be off an Enfield sniper rifle. Beside the word Alaskan on the side of the body is the number: 6721 & on the turret another number 7634***. Is there any truth to this & if so, do these given numbers put it on an Enfield? And which one? Thanks for any help...

that is a US G.I. scope, or at least the covers are. M81

It's definitely not Enfield or it wold have a post-type reticle, not crosshairs and target dot.

Thanks for the info. I figured it was a commercial version but just wanted confirmation. I'll keep it just the same for another future project.
