Proof House Markings
Typically the Liège Proof House had their acceptance marks stamped on the left side of barrel lug and frame, and on the rebated portion of the cylinder, or on the elevated forward areas of the chambers of pistols with fluted cylinder.
|Stamped on most pistols throughout the production, embossed on the left side of the barrel lug, close to the wedge screw.|
|Inspector mark for rifled barrels.
Looks like an arrow pointing to the right, or a palm tree sideways.
These marks were stamped on the left side of barrel lug and frame throughout the production.
Crown over R (sideways):
|Mark for rifled barrels 1884 through Feb. 26, 1968 (sideways).
Pistols made after February 1968 to 1973 do not have these marks.
The mark was stamped on the left side of the barrel lug.
ELG over * in oval (sideways):
|Final black powder proof.
Usually stamped on the rebated part of the cylinder throughout the production.
Inspector marks (below) are noted on Centaures from 1959 to early 1968 production. These marks are * over capital (mostly) letter C, D, F, H,K, L, q, R, S, T, U, Y or Z sideways:
They are to be found on the left side of barrel lug and frame, and close to the ELG oval on the cylinder. It was standard procedure that one inspector marked one pistol, i. e. the 3 inspector marks on a given Centaure are supposed to be identical.
|Exception of the rule: A number of pistols in the survey with one of the two naval scenes on their cylinders have the same inspector mark on barrel lug and frame but their cylinders are stamped by a different inspector. Upon disassembly the serial number on the cylinder is usually not matching the gun. This indicates that an extra cylinder with the naval scene has been installed some years back.|
Inspectors’ marks, names and the years of duty discovered on Centaures are listed below. The Liège Proof house kept their inspectors’ names as a secret for many years but here you go …
Pistols made after February 1968 to 1973 do not have these marks because they were discontinued Feb. 26, 1968, but reintroduced only after 1973, after termination of the Centaure production.
|And finally, please, don’t be surprised to stumble over irregularly applied proof marks from time to time, like the caliber .44 stamped upside down on Marshal Model #13402 pictured on the close-up on the right above.
