Above the 118/35 is a large 540, this isn’t the serial number. Does this number have anything to do with caliber?

No, the >>540<< has nothing to do with the kalilbre. Probably an assembly # or subcontractor #. But what is interesting is the Imperial Eagle on the underside of the left tube which is more an Arsenal or Sauer type Imperial Eagle. Plus there looks to be a Schilling Forge mark partially covered by the lower rib on the underside of the right tube.

Can you give me an idea of date with the patent number? When did first Treff show up? May help with cartridge information?

>>Selbstspanner-Drilling mit drei Bolzenhammerschlossen zwei Abzügen und durch Stechen des Abzuges bewegten Umsteller<<

July 1898 if D.R. Gebrauchs-Muster No. 71381. But it doesn't look exactly correct or does it?

Can’t see a pic but date makes sense with Shultz load on schrot tubes. Treff design is much older than I had first read (1913)

when i happened upon this meffert drilling, with "alluminum reciver with ingraving"....i remembered the references to the dural receivers, and thought i would place this into this thread. not a wealth of photos, or information, but the gun seems in decent condition...

many years ago, when i kept a table at the astrohall (hgca show) for 10 - 12 years....there would be an occasional dural framed combination gun show up - i've handled several back in the day.

can't say that i have any recollection regarding the names on them - information in this thread seems to indicate that meffert was the primary source of them....and as this drilling shows, there could be many names marked on ribs/floor plates/etc. with all of them originating with meffert.

best regards,

tom

Leichtmetall Dural technology looks to have been driven(flown) by the aviation sector. In 1930 the Meffert concern decided to pursue the development of technology for a lighter weight drilling(possible 3 scatterguns in 16 or 20 bore) by skeletonizing the whole lot wherever possible. Then someone associated with Meffert, a Light-Bulb turned on & in 1931 they sourced 3 blocks of an aluminum alloy coined the name „Dural“ were sourced and 3 Blitz Dreilings were made as prototypes and sent out with a travelling salesman. Said Travelling Salesman returned with zero orders and Meffert thought they have waisted a lot of time, effort & money. Then 80 orders hit their doors and they were unprepared. The rest is history. They had to adapt steel inserts for the wear surfaces to round out the project.

I have made a cursory search for the culprit of „Dural“ but it looks to be a byproduct of WWI and was common in the aviation industry before 1924.

Too the first „Hubertus Dural“ actions had the name „Hubertus Dural“ inlayed in Gold and the actions were coated in Black Lacquer a hard anodizing technique was devised.
