A final note on the little brass tools:
As Pete stated, they will not work very well after 90+ years, which is perfectly sensible. They were not designed to adjust a screw that has 90 years worth of crud and rust lodged between it.
I used the small brass tool with ease on the rear sight screw of a badly pitted, LP08 warhorse. But I couldn't free up the front sight screw which was rusted in place.
So I guess the most interesting question remains: Has anyone actually seen proper, era documentation of the sight adjusting tool? Are there complete WW1 armorers tool kits around which contain them?
Without proper documentation, the items we take for 'LP08 sight adjusting tools' may just as well be Zundapp Carburettor Adjusting tools
