I thought the correct rear sight for the No7 rifle was the standard Mk1 Singer backsight set at its lowest position of 200yds, it is only the N9 rifle that has the 25YDS etched on the rearsight, or am I wrong?

Wrong I'm afraid. If a bog standard sight is fitted and set at it's lowest point it'll shoot too low and you won't get a foresight low enough to compensate.
A little RAF shooting handbook said, in as many words, that the rear sight was calibrated so that it would be possible to zero the rifle in all conditions while using the full range of foresight blades. I'll see if they've still got it. But the No7 definately has a standard 2 - 13 Mk1 backsight (NOT a No8 25-50-100 yard and 'H' sight) marked 25 Y or 25 YDS on the left side
I stand corrected Peter but I was quoting in part from Skennerton on the Rifle No7 Mk1 who states "Intended for use at the 25yd range, the standard Mk1 (Singer) backsight is set at the lowest position of 200yds; to compensate for this, the foresight has been slightly reduced in height." it does not mention a 25yd mark neither does the picture on page 507 show a 25yd mark. However the N9 Mk1 rifle is definitely specified with a rearsight marked with "25YDS"
I've just read the old RAF EMER you refer to Buccaneer and blow me down......., you're right! I mean exactly right in what you say....., BUT! So I took an N9 onto the 25m indoor range over lunch time and at the lowest range, it does shoot too low. That would seem to confirm that the No7 sight does indeed have a 25yard marker on the left side.
AIncidentally, the RAF EMER also says that some No7's have solid new made barrels (my BS1740 does.....) and some, made from new bodies, are manufactured without the original No4 ejector screw hole. Interesting. Does anyone out there have a 'new build' rifle without the ejector screw hole?
BS1892 with solid barrel & original No4 ejector 'hole'

I owned only one of the No9s serial number A2799. Had a P-H flip up rear sight with windage adjustments. I am trying to track the gun down, but I was told the owner died.
