I guess I'm first on the scene, so without seeing more of the receiver and the mount bases (aka "pads"), hard to be sure if the rifle is a genuine T, but if you bought it "many years ago" it very likely is as hardly anyone bothered to assemble then and there was no supply of after-market pads anyway.
The scope is an REL MkIA or MkII. Can't be sure myself
The bracket is the roughest REL example I've seen, but as you have cap serial number "1" (and I assume "2" on the other?), and the stamps are on the opposite from normal side, you may have a very early REL bracket indeed.
That would tend to suggest a MkIA scope, if the two are original to each other. It looks like when whoever stole the scope was filing the numbers off, he filed the bracket edge as well, so yes, probably been together from the start.
Not sure what to make of the electric pencilled SN on the receiver wall, doesn't look like a
UK
FTR re-mark and doesn't match the original SN on the butt socket.
BTW: Faststone ImageViewer is a great free and safe download which I used to tweak your photos in about two minutes. Has features normally found only in pricey photo software. Try it out?
