Unfamiliar barrel marking - School me!

Zamo · 12-30-2009, 05:10 PM

I just bought a new 1914 DWM, and upon examination, came across a marking I can't place. In addition to the serial number, bore diameter, and barrel index mark, there is a 30.30 stamp on the barrel. I do not think this has to do with Winchesters or deer hunting (figured I'd better pre-empt that joke), but I'm clueless as to what it is. It is exibiting sufficient "halo-ing" that it seems period, but I can't figure it. I thought it might be some form of British proof, but there are no other non-standard stamps on the pistol to reinforce that. Any info?

George Anderson · 12-30-2009, 05:13 PM

The stamping is "Bo.30" indicating that the barrel was Austrian made Boler Steel. It's not uncommon on 1913 and 1914 P08's.

Zamo · 12-30-2009, 05:15 PM

Thanks George, that was quick. I'll post some more pics of these neat ol' hog-leg when I actually take possession (Gunbroker transaction).

In those days, Böhler had a subsidiary in Germany which was under control of the same group that was controlling DWM.

As promised here are a few pics of the pistol now in my clutches...

and

aw heck, how about one more?

sheepherder · 01-06-2010, 08:37 AM

Great pic of it disassembled!

I'm often annoyed at Luger/Mauser/anything owners who are afraid to disassemble their pistol...they usually end up posting about problems they are having...

Norme · 01-06-2010, 08:45 AM

Nice clear pictures of a very nice looking Luger. In the takedown shot it looks like the rear toggle pin has gone missing! Regards

Zamo · 01-06-2010, 01:07 PM

HA! I was wondering who'd notice that. I noticed it just as soon as I put the camera away and began reassembly. I wasn't inclined to re-arrange everything and try and take the shot again just for the pins sake. Norme wins the "attention to detail" award of the day!

Thanks for the compliments. It is a nice pistol, and looks even better in person. The photos show some oxidation on the barrel that is all but invisible to the naked eye in normal light. I was surprised to see it in the pictures and had to re-examine it up close to make sure it was there.

Usually they are engineer types

Nice looking luger !!! (and this is a normal strip down for me, I meant, completely apart)

Cleaning off 65+ years of crud...Stoning trigger/sear surfaces...Removing burrs...Cleaning off old built-up brass leavings...

Yeah!!! I love trains...

The last time I visited the National Battlefield Park in Gettysberg, my last wife & I took a ride on the old coal-fired locomotive train there...It was a riot (well, us goofing off about it was)...Wooden pax cars with church pew seats...Engineers with lunch boxes big enough to hold a bottle of Jack Daniels...(maybe two)...We had a blast...Broke up everybody in our car...

Christian,

Beautiful gun and of course very nice pictures of your Luger disassembled.
Congratulations.

I hate to be a gadfly, but the halos on this one look weird, as though they were created by an application of bluing remover to each digit, all nice and even and rounded; also a bit larger than one might expect to see. What gives?

Edward Tinker · 12-29-2013, 02:14 PM

Last time zamo visited was in september.....

Zamo · 01-14-2014, 02:07 AM

Yeah, so there.

Ben M. · 01-14-2014, 07:49 PM

what is the number that is after the Bo stamp. is it a code for metal makeup or an indicator of hardness of the barrel?

ithacaartist · 01-15-2014, 09:13 AM

The next number down, 6xxx is the serial number; the number under that 8,82 is the land-to-land measurement of the bore made at the factory.

Ben M. · 01-15-2014, 10:11 AM

sorry. what is the number just after Bo. what does the 30 of Bo 30 indicate?

Norme · 01-15-2014, 10:58 AM

Hi Ben, The #30 is the hardness number on the Böhler Scale, a proprietary system devised by the eponymous Austrian steel company. It's similar to the Brinell scale used here in the US.

Your gun main spring linkage pin is drifting to the left pressing against left grip.
Million dollars chip is likely to occur if you shoot that gun. Push the pin back in and you are good to go.

CAP Black · 01-16-2014, 09:19 PM

That sure sounds like a very helpful hint and quite simple. I await the outcome.
