Holy smoke! If this isn't the Mother of all keyboards...

Wow, fockstha? Oo

I'd bet on early homebrew for a really early do-it-yourself kind of computer enthusiast.

The original Apple computer didn't come standard with a case or keyboard. And things like the Altair 8800 were so bare bones you'd have to make the interface to connect it and the program to use it with.

Certainly a cool beast.

[Edit:] I saw K155 on the chip  (the last two characters appear to be A3, but I can't quite tell. The character before the 3 might be Cyrillic).
Looks to be a Russian equivalent to a 74 series logic chip.

[Edit 2:] There appears to be some markings on the PCB. It appears to be duplicated and stamped. Although IDing it likely won't help very much especially if it's homebrew/low production custom. That said it seems to be "K85" or "K35" with a logo above it separated by a line.

Looks like something fallen off a church organ - the type you'd play with your feet

LOL! If Bach had owned a computer keyboard, that's what it would've looked like.

Hmm, it is in Germany, isn't it? You don't think...?

You can't find wooden doubleshots like that anywhere. Amazing.
