What is the number beneath serial number?

howieb38 · 05-02-2012, 04:31 PM

On two of my Lugers, both 1939s, one a Mauser Banner Police C, the other a 42, there is the number 8,82 stamped under (meaning below) the serial number on the bottom of the barrel on both guns. This is the only place that the number appears on each pistol.
I can't find any mention of it when I Google it. Does anyone out there know what the significance of this number means??? I have other Lugers, but it only appears on the 1939 models.

This is the diameter of the bore from land to land, as measured by the factory and stamped on the barrel. You will sometimes see 8.81 or 8.83, but it is usually 8.82

Thanks for the fast and accurate reply. The site is a great place to learn about Lugers. It's a brain trust.

I ment to say, Thanks Alanint.

It is also in the FAQ, that and the 'stickies' at the top of each page (New Collectors area) and on other pages have some great info

Here is a cut from the blueprints showing the manufacturing acceptance tolerance... (If you want the whole set of blueprints, see the For Sale Forum Stickies!)
