Zkk 602 Jena scope

[M1008]

Found one, do they hold up to the heavier calibers?

Are the Jena scope on other Brno rifle interchangeable (the scope side of the mount) like a Zeiss rail?

I got one of those in a trade back in the 1980s.
It came on a .375 H&H BRNO ZKK 602.
4X fixed power, about 40mm or smaller objective IIRC.
The windage adjustment is in the screws at the front of the rail mount,
and there are little thumb screws like wingnuts on the right side of the rail for QD, on-off of scope from rifle.
---That rail was made integral to scope tube, somehow.
---Rail will fit the CZ 550 Magnum integral base/dovetails, same as BRNO magnum action.
Elevation adjustment is in the front dial on top of scope.
Rear dial on scope top is focus.
My reticle is a European No. 1 "Graticule"--- two broad horizontal bars and a lower vertical post with a point on it, that point at center of view, in the open space between the horizontals.
I used the scope on .338 Lapua Magnum to .500 A2 on BRNO and CZ rifles.

Only problems:
1. Recoil made the focus wheel on top of scope move. Scope has to be re-focused after each shot.
I managed that with a strip of duct tape across the focus dial to keep it from turning.
Elevation dial held OK.
2. The old optics and coatings are not as good as cheap scope glass nowadays.
3. Making windage adjustments by taking a screwdriver to the rail is not desrable.

Jena scopes are the nationalized production products of East Germany following WWII. Much of the pre-war Zeiss production capability was turned over to Soviet forces when Dresden and Jena were ceded to Soviet control. Those facilities became the nucleus of East German optics production. This production included lenses for various optical instruments, and scopes and binoculars themselves. When sold in the Eastern block, the products were marked "Carl Zeiss Jena" and when sold to the west, were simply marked "Jena." The lenses are as good as any produced prior to WWII - which was not really all that positive an attribute in the late 20th century. Scopes and binoculars are known for indifferent mechanical dependability.

What we now know as Carl Zeiss AG was founded in West Germany following the war, and obviously, has earned a well deserved world-wide reputation for building some of the finest optical products ever created.

Your scope is essentially a somewhat updated pre-war design. You will also find that it is neither fog proof nor particularly water resistant.
