Thanks for your input team. Much appreciated.
I’ll try a combination of what you suggested.
It seems that someone has had a crack at the rear sight method before me going by the marks on the base.

With regards the foresight. I have a Broad Arrow (issue)marked 0.060 blade, taller than that fitted. Problem is the dovetail is too small for the cutout in the ramp fitted. The ramp is marked thus :

No other markings on the ramp or blade.
So a combination of a smidgen off the rear base and solder on the front should see me right, provided the ammo used is a constant.
