If anyone knows more about this one feel free to comment (no need to login!). The look kind of reminds me of a Vermona '14 meets Baldwin Explorer.

Update: someone in the comments said it looks like a Minisonic 2. I think that might be it (see this post). The knob layout starting with the two large knobs on right match.

The following is the description from the auction. This is not a modular so obviously ignore that bit.
