I had one of these in 4x which I bought in 1990 from the US after reading an article in Australia Shooter magazine by Nick Harvey. They were made for the American market with a 1" tube that is machined out of a solid block of durallium which incorporates the turrent housings. Truly fantastic scopes.
The lenses are held together where necessary by molecular adhesion because they are perfectly flat to I forget how many millionths of an inch. Each scope is given 1,000 shocks equivalent to twice the recoil of a 457 Win magnum.
The turrent adjustments are given 100 turns around the square and must come back to the original point of aim. They utilize a carbide ball system similar to that which Weaver scopes used.
The scopes are tested in a vacuum chamber with water spray for 24 hours and must not leak or fog. The scopes are not nitrogen filled because they don't need to be because they're so perfectly sealed.
These scopes are way superior to the Conquest models in build quality. The modern Zeiss scopes have more advanced lens coatings, however they don't contain the superior lead glass that was used in this C model.
