Here's what I know; It's a Mauser action German guild rifle in 8mm-06. It's really pretty. Any info you guys can share would be much appreciated. I took it in trade, it's a beautiful gun, just not the sort of thing I'm familiar with.
I can't really tell you anything about the rifle, but I can tell you that "Flusstahl" means mild steel, "Krupp" is the name of one of the most famous steel and armaments corporations in history, and "Essen" is where they were located.
I see why you took it on trade, usually not my type of rifle, but it is stunning.
Outstanding craftsmanship and beautiful wood.
I don't know a thing about it.
Barrel proof mark:
1.) The crown-over-N is a typical nitro (smokeless powder) proof
2.) It is designed and proofed for a 13 gram bullet (approximately 200 grains)
3.) The bullet was St.m.G - literally Stahl-mantel Geschoss - meaning steel jacketed bullet
Receiver proof mark:
1.) The crown-over-N is a typical nitro (smokeless powder) proof
2.) The number is the weight of the powder charge in grams and the letters that follow are an abbreviation for the type of powder - (I can't make out the numbers and letters in the pic). This mark specifies the standard "full service" charge and NOT the amount of the proof charge.
3.) The bullet was St.m.G - literally Stahl-mantel Geschoss - meaning steel jacketed bullet
Just FYI - The other possible bullet types specified by markings are "K.m.G" for Kupfer-mantel Geschoss (copper jacketed bullet) and "Bl.G" for Blei Geschoss (plain lead bullet).
The other smaller markings I can't make out either, but these are more generic. There should be a crown-over-U (Untersuchung) meaning the marked part was inspected/viewed for defects (none found) and a crown-over-B (Beschuss) meaning a proof load or loads was fired (the marked part passed). The more detailed marks that I talked about first are caliber dependent. The final proof load for the finished product would have used the specified bullet, but with an overcharge of the specified powder. The amount of overcharge was a certain percentage of the service charge. In modern German proof law it is two shots with a 30% overcharge - no junk is getting past that! In the old days, the amount of overcharge may have been more or less and of course varied by country.
