Looking for some help/direction with a No 4 Mk 1 T

[Roger Payne]

I don't think the rifle has been refinished. Look at the sharpness of the stamps. You still see crisp rifles like this sometimes - little used examples. As everyone has commented it is unfortunately mis-matched, now having the scope & bracket off a U prefix 1945 dated BSA rifle.

It might not be so valuable as a fully matching example, but it's still worth money.
