The last handgun to carry Gasser's name was the 8mm Rast & Gasser Model 1898 service revolver (double action), adopted by the army of Austria-Hungary. This revolver was issued to NCOs and officers of the army. The M1898 was a very well made weapon that had several unusual features for a revolver. One was a method of stripping which was effected by squeezing and pulling down on the trigger guard and flipping the side plate open. Another was the very positive safety. This 8-shot solid-frame pattern had an ejector rod beneath the barrel. The Abadie-type loading gate on the right side of the frame behind the cylinder disconnected the hammer from the trigger when it was opened for loading. The trigger mechanism could be used in either a single or double-action mode. The angular Rast & Gasser had its grip too square to the bore to aid instinctive shooting. The frame is marked 'PATENT RAST & GASSER WIEN' above the trigger. The serial numbers are on the left side of the frame and barrel, an on the cylinder. During WW2 the M1898 revolver was still in widespread use in Central Europe and the Balkans, and numbers were in use with the Italian Army. The main reason for this retention was undoubtedly the high standard of manufacture used in this revolver.

Cylinder removal:

1. Turn the loading gate to the horizontal opened position
2. Pull the ejector assembly latch downward and turn it slightly, so it's side lug will lock it in position
3. Pull the ejector assembly and the attached cylinder base pin forward out of the frame
4. Remove the cylinder toward the right.

Rast & Gasser M1898 'ML' marked Revolver

Certain examples of these revolvers are found with an 'ML' mark on their cylinders and barrels.
The 'ML' stands for 'Molybdan Legiertem Stahl' (Molybdenum Alloy Steel) indicating a better material. The right amount of Molybdenum improves hardenability and reduces temper embrittlement of the steel.
All revolvers produced after 73400 have the 'ML' marks. Please provide serial numbers above 73400, which do not have the 'ML' marking and serial numbers below 73400 which have the 'ML' marking.

There are several alternative theories:
- The 'ML' mark indicates that the barrels & cylinders were made by Manufacture Liegeoise d'Armes as a subcontractor to Gasser. 'Wn' Austrian military acceptance marks were reported on Belgian 'ML' marked revolvers. Manufacturing dates indicate 1916-1918. ML was under German control during this time, so the subcontracting idea seems possible.

- Some sources claim that there are 'ML' marked revolvers in caliber 7.62x39mm Nagant. These revolvers are Belgian made copies of the Rast & Gasser. These revolvers have redesigned cylinders and the barrels to accept the Nagant cartridge and the barrel and the butt were shortened to make the revolver smaller. All reported 'ML' marked revolvers are in the original 8x27mm caliber so far, which gives doubt for this theory.

- Other sources claim the 'ML' to be an Austrian inspection mark. Why there are no similar inspection marks on other weapons manufactured at the same time at the same facilities?

If you have an 'ML' marked M1898, please provide your serial number, the caliber, markings, and date if any.
