Looking for info on the L42 L1A1 scope turrets

[Peter Laidler]

Valid point of course re curvature gauge that I mentioned but I was trying to keep it simple.

I would have to admit that the quality of work on some of the L1A1's that I have seen simply beggars belief. Nt so much the optical side but just the assembly afterwards with the over use of silicon sealant that.... anyway. Poor out inspection I say....
