What can you tell me about this No4 Mk1/2

[Dragonslayer]

So many questions and so little time.........

The parts you need are readily available from one of our own resident forumers here. Try Brian Dick at BDL Ltd in SC
The backsight is ranged from 200 to 1300 yards. None of this old metric rubbish in those days!
FTR is Factory Thorough Repair. That is a ground-up factory repair where the rifle was refurbished to 80%+ condition of a new rifle
You'll need to read some old threads to learn about the A serial number suffix
While you're there, you'll also learn about the trials and tribulations of the Fazakerley factory. But purely from an Armourers point of view, let me see how I can put this diplomatically ................... Have you ever heard of a Friday afternoon car? The Triumph TR7 was a good example of what I'm talking about. Well, Fazakerley built friday afternoon cars every day! That's only my opinion of course. There might be one or possibly two out there who will disagree

Ok, Thanks for the information. That gives me a clearer insight of what I have.
Considering that the rifle is probably not a collectible treasure and from the best neighborhood. Is there any reason why I shouldn't restore it to operating, sporterized condition for hunting? I'm not picky about prestine, original antique just accurate, functional reliability.
