Central Aperture Sights + others for SMLE's

The other side is points of elevation for reference. You can record these zero's if the range plate side doesn't work out accurately enough.(I always record these for given ranges as the range plates are not the best between 50 and 300 m).

I'm still confused about the "points of elevation", i cant seem to make any sense out of the numbers. IN the photo at 300 yards it has 0 points of elevation (i assume these are supposed to be zeroed at 300?) but at 700 it has 16 points. Is that so you can record indivudual distances at different rifle ranges (i.e X range may be 18 points at 700 yards and Y range 16 points at 700 yards?)

As a side note, does anyone know what the manufacturing issue that led to SAF Lithgow being struck from the sight?

There is a guy on gunboards who has written a book about these sights. Suggest you give him a try he is a range shooter.

Yes, the whole range scale might not be perfectly calibrated to your barrel length/load etc. With the "points" on the right you can clearly adjust from any position on the range scale in points/MOA. These sights were and are full bore sights and 300 is the shortest range, but with the ones I use for shorter range service shooting I suppose it's adjusted low, as I just ignore the range side and record the points for all ranges.

could have been on a marksman variant and disposed of later on, will confer with a mate of mine who seems to know a fair bit about marksman variants.
