Curta case question

From: Steve


Anybody seen a Curta (type I, late 1950s) with a brushed metal case? It's not black, it looks like unpainted aluminum or steel on the outside, and it's not smooth, it's rough, like brushed nickel or something. It's from the Van Nuys Curta company. The inside of the case is the black metal like all the others. Thanks in advance. -Steve
