It's real. Rifle serial is originally AS 9361. BSA late-ish 1943. Wood by Sykes Ltd (SL/N74). The Savage rear sight does look very brightly polished where the battle aperture has been removed, though many Savage made rear sights were fitted to 1943 BSA 4T's by H&H as they were supplied with a quantity to use on rifles that had passed the accuracy tests for conversion to T's but had come with Mk2, 3 or 4 rear sights. Bracket is a Dalgleish of UKWW2 production. Scope tin looks to have one or two minor Israeli mods as previously mentioned.
