I have a Hensolt Wetzlar Diatal 6X42 scope single turret adjustment but no instructions on making an adjustment. I have bore sighted the Merkel O/U gun but adjustments are needed, There are 4 screws in the turret one is silver which is the locking screw but I don't know what adjustments for the others ??

Meinherr,
GGCA member and friend Axel has addressed this a couple times with well written, clear instructions and hints regarding common problems caused by age of the scopes. I did a quick search to find his answers for you but am having a little trouble right now with my computer, including the loss of my "favorites". Since you didn't say what adjustments you need, I don't know whether I can help you now. If the adjustments required are to "windage", they can likely be made in the mounts. If the scope came already mounted to the gun, I suggest you try shooting it on a target before making any adjustments. If you mounted the scope yourself, bore sighting first is necessary, but if it is "close" adjustments may be delayed until after shooting on a target. A combination gun is very sensitive to one of the barrels heating up while the other is cold. When hunting, this doesn't make much difference but when sighting one in, it can cause much hair pulling and gnashing of teeth. It is very important to take your time and allow the barrel to cool. This is more important with a SXS, but it still is important with an O/U. After finding what adjustments are necessary, we can try again. BTY, it is also necessary to hold the gun in your hands while shooting at targets, don't rest the barrel on a "rest" and don't use a sling to steady the rifle.

Thankyou Mike. I used the laser bore sight but the adjustment required is elevation so I will fire some rounds to test it for 100 yards I had read on line that when you loosen the locking screw the turret will turn as it is knurled but mine wont turn. There are markings on the outside of the turret indicating that the claw mounted scope is lineup the factory ? Were most factory mounted scopes set at 100 meters?

Meinherr,
In my experience, most claw mounted scopes were not "factory mounted", unless ordered with the gun. Claw mounts must be precisely located for the particular scope and the scope us usually bought separately from the gun. The gunsmith that mounted the scope would have sighted it in according to the wishes of the customer. Sometimes this was 80 meters or 100 meters, according to the available rifle range. If a shorter range had to be used the gunsmith would usually adjust the point of impact at the shorter distance so as to have the point of impact meet the customers desires. Most often the sighting would be whatever distance above the point of aim it took to have the point of impact coincide with the ammunition's "point blank" range, which may vary with different ammunition. The way to find out is to shoot it.

Meinherr,
The scope may or may not have been mounted by Waffen Franconia Wuerzburg. The combination barrels may have been made or fit up by them as well. Merkel was located in the East Zone under the communists at the time and there may have been restrictions on importation of rifled barrels. In the 1970s I watched my gunsmith friend Walter Grass make combination barrel sets for Merkel shotguns because he could not obtain them from Merkel. Waffen Frankonia also had the ability to make such sets or fit up sets made by others. If you are able to get a build card, then, it may not include the combination barrel set.
