Not sure how much of the above is tongue in cheek. So, for those that take your comments seriously, I shall dispel a few myths.
1)
And despite the wonky action , it is surprisingly accurate. The myth that rifles with rear locking lugs are "wonky" and inherently inaccurate is just that, a myth. If you don't believe look at the accuracy that can be squeezed from a MAS 36 or a Danish M47.
2) ...
it is surprisingly accurate. Maybe not so surprising. It is made by Savage! A myth promulgated by the "American Stuff is Better" Society.
3)
The butt plate was indeed black painted zinc alloy. But I had an NOS brass butt plate in my parts bin , so I swapped it out. Might not be 'correct' but it sure is purrr-dee! The noise you can hear outside your house is the Enfield Purists Club warming up their tar boiler and shaking up their sacks of feathers.

4)
I've heard the Savages were generally more accurate than the Brit-made rifles and were often selected to be made into sniper rifles. More propaganda from the "American Stuff is Better" Society, I'm afraid. I'm am not going to say that Savage rifles were never selected to be snipers, because saying never when talking about milsurps is a quick way to get egg on your face. The great majority of No4 snipers were made at the BSA Shirley factory with some built using Long Branch rifles.
5)
But I've also heard that most Savages that made it over were never even issued , they sat in warehouses because the snooty Brits didn't want to defend the homeland with a foreign made rifle , let alone a YANK made rifle.
Your little rolleyes chap is dead on there. I suspect this rumour may have been started by some Brits with poker faces winding up their American allies over beers in the ETO. Also the UK was so short of weapons there was little chance of anything being left to languish in stores.
The Japanese on the other hand were funny about using rifles that did not bear the chrysanthemum mark of the Emperor. Many of the Italian made Type-I rifles languished in warehouses in Japan for that reason. The Japanese naval forces used them quite a bit but the Army seemed to want nothing to do with them.
Your rifle has seen service with the South African armed forces looking at the mark on the receiver. If you remove the wood you may find that the barrel has been replaced and stamped something like 61, 62 or 63, indicating the year. During that refurb they would also likely have changed the rear sight for a micrometer type.
You wood looks nice but I suspect it has been refinished. The edges looked rather rounded, sure sign of a previous owner with too much sandpaper lying idle.
