Rust on the head of a stahly live blade?

[Iakona]

I saw one recently at an antique shop. Was a decent deal I suppose - if I were to pick it up it would only be for the head. It had a bit of rust on it... are these things stainless, or nickel over brass, or something else?

I am not sure about the material, but any rust is probably from an old blade.

The wiki (http://wiki.badgerandblade.com/index.php/Stahly_Live_Blade) says that early models were chrome-plated, while later models were aluminum.
