That's an excellent idea. I will certainly look into that.
A quick update, Jonathan Ferguson, curator of firearms has kindly been able to confirm that seven No74 Mk1 scopes are in the Leeds Royal Armouries collection, with one mounted on a rifle.
There is a a good deal of information relating to the scopes and trial in the archive there and Ive been given permission to look through the documentation.
This really is a huge help and should allow us to form a complete picture of the project.
