I just found a pretty good description of the use of the Mann Device in Hatcher's "Textbook of Pistols and Revolvers", 1935.

I don't want to post the whole thing as I don't know who owns the copyright.

Anyway, a V shaped metal trough of steel is mounted on a concrete base. Elevation and Wind age screws are fixed to the trough.

A telescope is laid into the trough to get the trough "sighted in" then removed.

The heavy Mann Barrel (Hatcher calls it a cylindrical barrel) is laid in bottom of the V trough. Under recoil the Mann Barrel moves but the trough doesn't. For the next shot the Mann Barrel is laid back in the V, which automatically lines it up for the next shot.

The trigger is activated remotely of course.

Simple enough.
