A few quick comments:
1. the top rifle butt stock is contoured with the "standard production" "sporter Butt" pattern used on the C.No67 MkI telescope equipped rifles.
2. the bottom rifle has a "sporter butt" as used on some of the trials snipers.
3. the sporter with the Lyman sight has the
Canadian
War Assets disposal stamp on the top of the knox form.
4. a similar rifle was on display at the "Long Branch" site several years ago. It had the CWA logo on the side of the receiver. That one has an un-checkered stock.
5. the "SPECIAL STIVER MODEL" is a No1Mk3 action fitted with a No4 contour barrel with the lugs removed and a ramp added. Probably a use for the obsolescent rifle to be used as a hunting rifle.
