Pickett Envy: dietzgen gets into the metal slide rule game, to better-than-pickett effect. This is easily the nicest metal slide rule i've ever seen. It's not too heavy to use, it's readable, and in general it's just a really nice slide rule. The design (or at least the appearance) seems to owe more to the Lutz 252 than, for example, the Dietzgen 1734, the equivalent log-log model from dietzgen. Also, this one was made in germany.
I bought this one from D'Antiques Ltd. They're really nice folks.
