another signal pistol?

Question
Doug,
I just acquired a Walther UP Model 1, and can find no info on it. I believe it is a signal pistol from that era as well. Did you run across any info on the Walther during your research?  Thanks, for any help- Keith

Answer
Keith,

There is not a ton of info out there on these signal pistols.  I'd point you to a couple of sites for more info.

First, for a picture check out:

You also might find some interesting discussion on the Walther discussion forum.

Beyond that, there is not a lot more I can provide beyond the other answer you've already seen at this url:

Hope this helps you out a bit...

Regards,

Doug
