Hi Dean,
Yes...the Bobba book would have this info. and lots more.
I am away from my books, but if I recall the transition from "in the white" to "blue" interiors occurred somewhere in the 26000 to 27000 serial number range. There is usually not one gun number at which such a change occurs. Rather, it occurs over a range of serial numbers until the habit of factory workers changed or when pre-prepared parts ran out...
Parts of the 1906/24 W+F Bern are available...ones decision to shoot depends on your gun's condition and your willingness to risk parts breakage. The Swiss shoot regularly and did so with their lugers, so the guns are built for shooting. Personally, I will shoot every luger I own...even if a collector piece...just want to know it works...but this is a decision each collector must make for themselves. But I have several shooter lugers that I use 95% of the time.
The fellow I previously mentioned, Stefan Mahrer, and others sell luger parts on the Internet...so they are available and even show up on e-Bay from time to time. I just lost an auction for a spare 1906/24 magazine a few weeks ago. Other accessories for Swiss lugers are available if one is patient...
See a discussion thread a few months ago I titled "A Little Show Off Time"...for some of the goodies I have picked up over the past 2 years for one of my Swiss lugers.
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
