I remember reading about these but don’t remember where. Can someone tell me the significance of these marks? THANKS!

those are tooling marks left from machining the recess.

Agreed. Most likely from an end-mill cutter.

Fritz, the Mauser machinist, had a bit too much beer the night before and got a little sloppy with his work. Me thinks.

Thanks to all for chiming in, and especially to Ed for helping with my photos. I recently acquired this BW and this was the biggest question about the Luger.

On a side note, I’m wondering if there is a Recovery Group for Luger addicts? I wanted ONE (1) Luger. I’m now at 8. I’m going to the po’ house … but I’m going well-armed! ��

Sloppy work isn't the cause....it's the condition of the cutting tool and how sharp it is.

Tooling marks can also be seen on this C96.

velodog455~ is correct the marks are from an end mill machining process.
Luger's that have them have not gone through the final finishing stage ... this was due to war time manufacturing where the finish of the gun was less important than getting the gun to the soldiers @ the front.

I have never seen these milling marks on commercial Luger's but its possible.

As for your 'addiction' just be thankful you aren't addicted to collecting teaspoons or beer cans etc,

Fred Patterson · 01-18-2024, 07:04 AM

Well … yeah. There is that!
I feel much better now!

You have a beautiful 42 byf luger there. I have a byf 42 as well with a little more original bluing on mine. Mine has the wooden grip panels that match the number on the gun. If you would like to see some photos let me know.

all of the above info is true concerning the "END MILL" cutting tool, however those marks appear to me to be caused by the "END MILL" flexing as it cuts the material, which usually results from the speed of the bit as it though the material in relation to the speed in which the bit is turning.

even a sharp bit being pushed through the material faster than the bit can cut will result in the bit flexing leaving gouge marks deeper than the level that the bit is set at.

just my 2 cents
