Dumoulin Magnum Mauser Action Help

[woodsman1991]

Good evening, came into possession of what appears to be a Dumoulin square bridge magnum Mauser action. Does anybody have details on where these were built and when? Were they Chinese made, similar to the standard length Dumoulins that Sarco sold recently?

The magazine box is 3.84 inches, ejection port is 3.5 inches long. Any info one this would be helpful! 375 H&H fits inside with room to spare. Bolt face is H&H, ejector blade is oversized still. Brand new and unused.

Interesting, I haven't seen one that is a magnum length.
Do they have any more where you picked it up?

A good friend who does all of my rifle and gun smithing work came across it at a small gun show this weekend. An old guy was clearing out the last of his table and my friend knew that I had been looking for a magnum action for a long time and snagged it for me. I've never seen one like it before and it was the only one there.
