I think the jpgs of the SouthOrd Pickgun that Shrub refered to were lost when the poster closed the site that he had them posted on.
Maybe you will have better luck ...

While I have a copy of them, I do not have permission to repost them.
The link to a German Site that Bemble gave us, is to an amazing site.
Lots of stuff of interest for the info junkie, like me, that wants EVERYTHING out there on locksmithing/lockpicking.
Indeed there are excellent jpgs of the Wendt Pick Gun with acurrate measurements.
I do not speak a word of German, but with the translation tools on Google and Altavista, I had no problem registering and checking out the site.
