Sorry, that thing looks like a Leica crossed with an enema nozzle.A rectangular enema nozzle in the rectal passage ... most intriguing and disturbing observation ... I sincerely hope you aren't speaking from personal experience
My dear man, "crossed with" not "into". It retains the properties of both.
However, I retract my statement, and say that instead it needs a charging cradle and a little stiff cleaning brush. Looks more like a first gen rechargable electric shaver (ca. 1974) to me.
Either way, its bfu for a Leica, which is in and of itself, a piece of elgance. Don't think there's much more elegant in camradom than an M3 with a 50 Summilux on it.
