This capable anti-tank gun was used in large numbers (339) in casemates and infantry blocks of ouvrages. The gun was suspended on a carriage attached to a rail mounted to the ceiling of the firing chamber which allowed the crew to slide the gun back and forth in order to swap the AT (anti-tank) gun for a JM.

Unfortunately for the French, German tanks were never at the receiving end of this formidable gun.
Today, examples of this gun can be seen at (among others): PO La Ferté, GO Simserhof, and GO Schoenenbourg.
There are reports that moving this gun into it’s embrasure had to be done with care.
