The Lafette wrench - What does it do?

Postby JBaum » Fri Nov 03, 2017 8:06 pm

Attached are some pictures of 3 variations of the lafette wrench, and what the wrench is used for on the lafette. Since the lower part of the MG34 lafette is the same as the MG42 lafette, the wrench works the same for both.

The Norwegian wrenches are easier to find, and not as collectable as the German wrenches, so they aren't nearly as expensive. The German wrench often sells for $200 - $250, depending on condition.

Three variations of the lafette wrench. On top is the Norwegian post-war wrench, made by the Norwegians for use with the surplus German equipment they got after the war. It is immediately recognizable by the large part numbers stamped in the side. The middle (WaA 127) and bottom wrenches are German war-time production. Each has a waffenamt stamping. The bottom wrench has very faint WaA 142 stamp just to the right of the dot marking (easier to see by clicking on the picture to enlarge it).

The arrows indicate the pin holes in the adjustment for the spring tension spring inside the cylinder. This spring tension adjustment is used to control the amount of movement of the gun cradle, which is used to operate the searching fire device.

The pin wrench is in place in the pin holes. The two sides of the wrench have the pins oriented 90 degrees off from each other, allowing the adjustment to be made 1/4 of a turn at a time in the limited space. Compare the top and middle wrenches showing the two sides in the first pic.

This bolt looks like it goes straight into the telescopic sight base, but it is loosened to adjust the cradle finger which operates the searching fire device.
Wrench2.jpg
The wrench fits on the telescopic sight adjusting bolts.

The open end also fits on the adjusting screw for the finger which operates the searching fire device. A flat plate washer is bent straight, the finger is adjusted, and the washer is again bent over one of the flat sides of the bolt to lock it in place.
