Req. information on JRS Drilling - 01/24/12 01:31 AM
I have a drilling Double 16 X 8.7 Marked only RWS with lever under trigger housing to open and can find no info on this. Can some one help w/ info and perhaps value?
Re: Req. information on JRS Drilling - 01/24/12 02:26 AM
Not many clue there! The JRS only means that it is 8x57JRS cal for the rifle bbl, 8x57 Rimmed with .323 dia bullet. Pictures of the watertables (action flats) & any markings on the bottom side of the bbls from the breech end to the forend hanger will reveal more along with overall pic's of the gun & action.

Post 1912(& prior to 1923) Roux type Dreiläufer in 9.3X72R(tight) by someone like R.W. in Suhl. Any more marks or initials around the forend hanger?

It was proofed/proved in Suhl with a 13 grain bullet. M4 was trying to direct me but I don't see the JRS. Some choices for R.W. are Richard Wagner although I don't know if he claimed Suhl or Zella-Mehlis as home, Robert Werner and I'm sure there are others.

Sorry I ment RWS and not JRS "my bad"

Loco Pirate,
No need to apologize; you typed RWS the first time.
I can see the JRS thing popping up in ones subconscious though, especially with those of us dialed into the German and Austrian guns.
I suspect your gun is a JR (.318") but by all means slug the bore to make sure. Launching a JRS (.323") down the bore, if it would chamber, may have some unsavory consequences ... to say the least.

There isn't a 0.318" possibility in 9,3X72R. Maybe a 0.355"

There you go, now I did it. I took off on the .318"/.323" following on M-4's response. It can happen.
Raimey is right with 8.7 being well over that of any 8mm. The true conversion of 8.7 mm to inches being .3425". That being so you have a 9 mm variation.

I had already confessed my error with the owner via PM after seeing the pictures of the bottom of the bbl clearly marked 8.7x72 
I should know by now to withold comment until all available informatation has been reviewed. My bad!

My very similar looking Drilling is also marked 8,7mm (clearly it’s bore diameter, not it’s groove one), but what exactly did that mean? I fitted a recently made 9,3x72R cartridge down the tube and it almost fit. I asked my gunsmith to do a chamber casting with Cerosafe. Measured close to the land impressions, it was .364”, corresponding to the typical 9,3x72R bore. So although it's marked 8,7mm but it's certainly not a 9.0mm.
I later obtained a copy of the Gun Digest 1955 article “Proof in Modern Germany”, in which Baron von Engelhart stated: “The very commonly used 9,3x72 (now called 9,3x72R), frequently was marked as 8,7 and similar”. Evidently 8,7; 8,75 or 8,8mm descriptions were also used for the same cartridge.
There are also 3 variations on the 9,3x72R chamber, (called E, D and Normal), and, with the correct FL sizer die set from CH4D, it will now readily chamber modern S&B 9,3x72R cases after they have been full length sized and also after their rims have been thinned. I have here cartridge drawings showing the difference between the D and E cases.
Perhaps this will be of help. If you do prove to have a 9,3x72R, the bullets are smaller than 9,3x62 and 9,3x74R, so be caseful about that also. S&B and RWS both make them.

Chasing something else like the Beckerflinte, Becker & Holländer Waffenbau or just info on Becker and found some RW and RWS initials that caught my eye. RW and RWS just might be for Römerwerk Waffenteilefabrik for a finite time span.
Vorbohren, bohren, reiben und honen - sources give that a large percentage of tubes at one time originated at Römerwerk Waffenteilefabrik(1921-1931?)- Some give an origin prior to WWI. Friedrich Wilhelm Heym looks to have heavily sourced Römerwerk and owned or absorbed it at some point(1931-1938).
"Jacob Roehmer, Suhl was the manager of the "Römerwerk", mostly a machine shop and parts factory supplying the guntrade, though they made guns of their own too, like the unique "Roemerpistole",which could be converted to a selfloading rifle, or the selfloading "Beckerflinte" shotgun. Many "name" gunmakers like Dornheim, Greifelt, Thieme & Schlegelmilch, Stadelmann, several Kesslers, Funks, Jungs were shareholders."

I believe Emil & Ernst Kerner, Christoph Funk, Thieme & Schlegelmilch-mentioned above(later owned by Alfred & Ernst Funk), F.W. Keßler(mentioned above) and a few others also sourced Römerwerk.
