Scope production never got up to 30,000. It looks to possess original parts - the body pads look genuine (the front pad looks typically very late), the rear pad has been off & on again, or at least its screws have. The cheekpiece looks to be from a very early converted (4T) rifle (note the extra 'notch' at the bottom front not usually seen on most 'pieces - I've seen a few like this now, & some were made from birch rather than beech). If it is an early H&H conversion of a Savage Mk1 then don't necessarily expect to see the D6E examiner's stamp in the usual place. The serial number is not in my copy of 'the list' but mine might be incomplete. I'd be interested to see what Simon says when he gets a chance to have a look.
More clear photo's of the body pads & the milling of the body for the front pad would be nice, as would the back of the body/bolt guide way area (you never know, someone might have added a bogus D6E!!), & the under side of the body showing the mag well machining to accommodate the 7.62mm magazine, or lack of it.
Hope this helps.
