After taking my rifle completely apart, I was delighted to find the wood and barrel in fantastic condition. I was less delighted to find fresh stamping on the bottom of my mechanism, and now I'm just confused. On the bottom of my whole chamber assembly is stamped:

6.5x55 MM
M/1912
CU INC
OMAHA NE

My barrel happens to be in superb shape inside and out, which led me to think this may be some sort of refurbishing company? Any attempt I make to research the company comes up with nothing. After this, I found another set of stamped characters, these looking original, that included the letter F, followed by a counterclockwise swastik symbol, and then either a letter I or a number 1. Below this is the number 16. Any information on any of these marks will be greatly appreciated, and I will include images of both sets!

First set

Second set

I think the second set is easy, original when the receiver and barrel were assembled.
The second is perhaps a verification on the chamber size with the company that did the check? If you really have doubts have the chamber cast.

I've shot the rifle, so I know the chamber is 6.5, but the serial number puts it as assembled in 1918.

'Brian B' - The 'Swastika' symbol is for the Norwegian steel supplier.
It was applied long before the Nazi movement in Germany and has nothing to do with National Socialism.

The Omaha dealer and caliber marking is likely a post 1968 U.S. importer stamp.

I see!
