Uuuh.. Hi Guy's.. I was just passing through and saw my name up in lights. I'm some what in awe.. I was going to get her in my hot little hands first.. I want to make sure I don't have a sow's ear, you know how things can turn out when you purchase off auction.. Perhaps Luv2 would be kind enough to post the pics he has?... I'm a computer idiot! I don't know zilch about the maker, and still need to find claw mounts and scope, perhaps you guy's can help me out?

Thanks All

Sorry guys, but in Kalifornia there is a 10 day wait/registration period.. I will try to get a photo op lined up when she's in my hands.. But I must say, things are better than I could have dreamed for.. But in the mean time a couple of questions for the Mauser info guy's..

Anyone know of this maker? S.WINIECK I. POZAN

And what does the Barrel marking say in English.. FLUSSTAHL KRUPPESSEN

I think it means.. Fluid steel Mfg.By Krupp

Thanks all

Yep, "flusstahl" is fluid steel made by Krupp in the city of Essen, where Krupp was located.

Thanks 333jeffery

To take the "FLUIDSTEEL" question one step further.. Wasn't that the old school description of Hammer Forged??

No takers on this question....Who is this maker?? S.WINIECK I. POZAN

I think that writing is Polish. My guess would be that the first part was the gents name and the Pozan is for the area of Poland. Kind of the same as Krupp Essen.

My knowledge of "fluid steel" is not that great, but I believe it originally referred to barrels that were cast rather than the old Damascus steel barrels that were made by pounding strips of metal together. The folks that are experts on this subject are the old shotgun collectors. They're always discussing the pros and cons of each method of making barrels.

333jeffery,

I don't think a "casting" would make it too long in modern hi pressure cartridges..

Casting would just be the first step. After that, the metal would be forged into a billet, which would then be machined into a barrel. That's not the same as "hammer forging", which involves taking a metal tube, putting it over a mandrel, and using a special machine to form the barrel by compressing it over the mandrel. I'm probably missing a good bit of detail here, but that's what I know about making barrels. I believe hammer forging wasn't used to make barrels until the 1930's.

Fluid steel or fluid compressed steel is a different breed of cat.

The problem is to offset the thermal contraction as steel passes from a liquid to the solid state.

If you pour molten steel into a cruicible, then let it cool, the steel forms a funnel shaped vortex in the center of the cast mass. Aside from the void in the center, the steel has an open crystalline structure because of the thermal contraction.

It was learned in the 19th century that if you pour the molten steel into a crucible with collapsible sides, and as the steel solidifies, you compress the sides of the crucible with hydralic cylinders, the steel is compacted so as to have no void, and the crystalline structure is more dense. The result is a much stronger steel. This was "fluid compressed steel".

The concept caught on throughout the advanced world, and it remains in practice today.

My dim recollection (obviously wrong) was that while the steel was in a semi molten state, it was squeezed through a mandrell (imagine tooth paste squeezed from the tube)into a ingot form, from there it was hammered into forged ingots later to be machined into anything from rifle barrels to an artillery barrel or whatever.. Sorry, I should have made myself clear.. I wasn't refering to hammer forged barrels as we know them today..

Thanks Jeff and Curl..

That stupid little question was nagging at me..

That stupid little question was nagging at me..

During forging operations, you want to stay well away from a "Semi-molten" state. Forging is done at a super-critical temperature, high enough to allow maximum ductility, but low enough so that the material will not overheat. The forge operator (forger, forgest...?) must monitor the temperature closely so that the mechanical work imparted to the forging doesn't exceed the allowable temperature. This thermal spike can result in a phenomenon known as "incipient melting, or grain boundary melting". Grain boundary (G-B) melting produces a "hot short" condition; the material can literally fall to pieces. Not good. G-B melting is a fatal flaw that cannot be remedied by any means - the steel must scrapped.

G-B melting was supposedly one of the causes for the notorious brittle steel used in low-numbered Springfield 1903 Actions. There were other causes, to be sure, but lack of adequate temperature control during processing ranks at the top of the list.

Posen , Poznan , Pozan , was used after about 1815 , it refers to the ( at the time ) largest district or region of Prussia , it is also a city in the district .. It is a German translation , of Greater Prussia or something close to that ..

I'm also thinking that the name maybe S. Winiecki ..
