I need an antique expert . Probably i have something worth.

Hi there!
I have bought this a few months ago.
I fell in love at first sight.
It's both sides full gold plated. Every element is gold plated!
All is handmade- even the "titles".
A few days ago i saw at e-bay that one element from this board ( the red one) is worth 8,50 $ :O
i don't know how is this- an ancient computer?
But i want to know if there is an y antique expert on this forum and could tell me how much this is worth.
I would be very grateful.

ps: I am from Poalnd so sorry if i make gramatical errors.



I add 4 photos of the board:
