HELP - ID this prototype (?) LB sniper scope & mount

[Lee Enfield]

I'm more interested in the No8 tin...who made it? is it dated?

The fact that the front ring doesn't appear to fully grip the scope tube, while the rear ring appears slightly undersized leads me to believe that it is a (fairly) recent assemblage. No one would seriously expect to have done any sort of honest assessment based upon improper clamping of the rings.

Are you sure the rings are real? much of the filing appears to be in places where the cast indian/Chinese copies differ from a real LB No32 set of rings.

My understanding of the 1943 trials reports is that there were a number of Lyman scopes utilized which are (so far as I know) unknown today.

I think anyone who had access to experimental? Lyman scopes from an actual optics manufacturer would not be impressed by this representation.

I am however intrigued by what appears to be windage adjustment contained in the front lense cage ala m.1917

what is the diameter of the scope? Is the scope optically useable?
