It been redone quite clearly. It doesn't have an aged Linseed coating on hence the lack of the red tint. The metal work coating is totally wrong for every Lithgow I owned, handled or read about, the markings have been clearly obliterated, including those you should easily see on the right side of the butt socket. I can't make out the serial code on the handle there. If anyone can determine that one it be pretty easy to tell when that part was at least made and where. The serial number also been obliterated from the receiver just before the barrel. No Lee Enfield would be made without the markings. It just not Commonwealth practice.
What I suspect here is he parkerised the rifle, destroying the markings, sanded it down really smooth, and then stuck on a couple of coats of finish. The story attached to it is 99% sure is bs and any historical value of the rifle has been really damaged. Should still be a good shooter than if the barrel is good. Should be worth in the $150-200 region around here.
