Many thanks Jani for the assistance. I did find that in 1910 that the Poldi AK - Antikorro/Anticorro was patented and possibly obtained a trademark for Poldi AK - Anticorro in 1910: http://www.anticorro.cz/english/items/history.htmhttp://www.anticorro.cz/english.htmI can't say if Quickstep Anticorro is a subsidiary of Poldi or what the association might be.

Robert Schrader of Göttingen(founded firm 1885) had a patent on September 10, 1902 for drillings with rifled tubes of lengths 40 - 50cm and scattergun tubes near 72cm(I'd like to see the patent to see the actual range). Robert Schrader had several patents and his drillings were complex with odd features similar to Brenneke's. Baron von Münchhausen was a client of Robert Schrader's and was a fan of the 40-50cm rifled tube on a drilling. Schrader more than likely sourced the craftsmen of Suhl.
In Florence, AL today I saw a rough condition Robert Schrader Göttingen hammer drilling with what I guess to be a 40cm rifled tube that had it's own menancing muzzle beneath the scattergun tubes and the short rifled tube had "DRP" in script on the tube so it may have been as early as 1902. The calibre was 9.3X82R and was stamped on the extractor side much like those seen on Teschner - Collath examples. Kind Regards, Raimey rse

Here's an image from a 1920s(I think) Brenneke catalogue of the Musselshell lockup and following are proofmark pics of Mark Baumgarten's Brenneke safety drilling with Poldi tubes. There's an article in GGCA publication No. 22(Summer 2004) detailing Mark's father and the receiver.  Anyone know what currency units the "Cr. 1000" might be?  Interesting that some function of the tube making was performed by Valentin Christoph Schilling on this Suhl made drilling. I wonder if ole Konrad Heym was still involved. The rifled tube at 65cm is a good deal shorter than the 72cm scattergun tubes.  Poor effort at an image capture of a 1910 Val. Chr. Schilling Advert The reason V.C. Schilling had a hand in Baumgarten's drilling with the very new Poldi Antikorro tubes was that he was an outlet and may have had the monopoly in 1910. Kind Regards, Raimey rse

I have found that the next line in the above advert is und Paul Scholberg Lttich. It notes that if you have spezial steel needs for sporting weapons, you will be well satisfied to source either Schilling or Scholberg. So, Carl Bittiner was a sourced for Bhler tube steel and I believe was at the same address as Paul Scholberg. V. Chr. Schilling was the only game in town early on for Poldi Antikorro and that is why we seen his initials on Baumgarten's Brenneke with Poldi Antikorro tubeset #280. I think these tubesets were sequential but don't know just how high the number grew. But Paul Scholberg was the source in Liege so if you have a sporting weapon with Poldi Antikorro tube steel proofed in Liege, the probability is very, very high that Paul Scholberg was sourced. Note on the Paul Scholberg boxlock below that his control mark(trademark/whatever) is rotated 90 on the underside of the left tube.  Poldi Antikorro steel tubeset #2944  Circa 1910, I've seen info suggesting that Scholberg & Delheid had a successor and I assume it to be Paul Scholberg as he seems to have hung out his shingle at this time and begins to apply from DRGMs in Germany. 432830 DRGM circa 1910 555??? DRGM circa 1912 566991 DRGM circa 1913 U.S. Of A. Patent 1982401 for 1932 I'm sure there are more & I'll add to the list. Kind Regards, Raimey rse

 1928 Advert for Paul Scholberg - Record & Regina(sideplated boxlock) Apparently he was the successor to Scholberg & Delheid as he peddled Rekord sporting weapons and used Record for his telegraph address.  Kind Regards, Raimey rse

As usual I was looking for something else and stumbled upon info from 1915 that gives the Poldi Antikorro steel has the following components:
0.145% Carbon
0.45% Silicon
0.50% Manganese
9.78% Nickel
Kind Regards,

Kind Regards, No Chromium? Poldi-- from Leopoldina Wittgenstein-- whose husband was an Austrian nobleman who developed the anti-korro/corro brand of gun barrel steel- the five crowns stamp sometimes seen on their trade mark may refer to his desire to have his steel exported and used by five other countries besides Austria-

Francis/Fox:
I'm sure it contained Chromium, I'm just not positive of the correct percentage. The 1st stainless/Antikorosnl oceli (Rostfreie Sthle) was exhibited at a Vienna Hunting Expo in 1910. Some time later, possibly 2 years, the value of Chromium in AKC was at 25% and the Nickel content was increased to 20%. The following may be present:
Cr, Ni, Mo, Cu, Si
In 1914 Ludwig Wundhammer notes he has had Poldi Antikorro tubes in stock for over a year and has rifled tubes for the New Springfield in 22 Highpower as well as Mausers. At this time Mr. Stewart Edward White is supposed to drop off his African Springfield to be fitted with a Poldi Anticorro tube.

I'd guess that the stamp "POLDI ANTICORRO No. 280" is a steel type recipe, which was evolving at the time. It appears that Karl Wittgenstein's Poldi Hütte Kladno facilty(Krasna Poldi - Beautiful Poldi poem) in 1910 was the 1st to turn out stainless steel( Rostfreie Stähle ) and there were a couple of variants like AK(AnitKorro Stahl), AK1, AK2, AK3, etc. Poldi Anticorro contained 10% nickel was acid and corrision resistant to the point that it took 5 to 10 times the application of rust bluing for the finished product. Baumgarten's Selbstspanner Sicherheits Drilling Patent Brennke took a great deal of effort which may have been a year or so in the making and it may have begun as early as 1910, the 1st year Poldi's Anticorro was produced. So the drilling had the latest and greatest steel type recipe at the time. There was nothing short about this drilling and the price reflected it. Circa 1900 the Poldi Hammer hardness tested was developed and the following site has an interesting description: http://www.alexdenouden.nl/08/poldi.htm Kind Regards, Raimey rse Okay, meine Freunde, ich werde es versuchen hier. Vielleicht 90 Prozen rechten?? Usage/Application instructions and number plate for the boiler pressure method of Poldi--last word confusing Hutte- umlaut over the u-- usual meaning is Hut or cottage-- Anyway, perhaps the German/Austrian form of our later DHP penetration hardness tester? Can you shed any light on this Raimey- Danke!!
