Peter Please - L42A1 Scope Tool?

[Badger]

I'd like to know what it DOES?

I may be missing the obvious here, but I assume it's just a "home made" version of the regular No.32 Mk1 Sight Adjusting Tool, which consisted of a double "T" handle wrench to adjust the elevation and windage dials. Although not needed, it perhaps it just made the job of adjusting the dials a little easier than using other tools?
