That's the real deal, beautiful original rifle.

Mismatched scope/mount to rifle (very common), but otherwise all correct.

Sum of the parts: Mk3 scope=$1500-$2000
original mount: $800-$1000
No4 T rifle: $1500-$1800

All prices US, based on on-line auctions and ebay.

Condition is everything, so that rifle might bring more. If the range/deflection drums are frozen, plan on an expensive repair.

Hope this helps.
