AFAIR 1541C needed one bit to be grounded on the VIA port...

Right - that's what I meant by writing "hardware add-on for copying disks" ;-)

The conclusion so far is that if that's a 1541 expansion then it is either a proto of TT with VIA port tapped on separately or - what I tend to believe more - a copy station hardware. In the latter case, the "industrial setup" could possibly even get along with drive case remaining open as Ruud mentioned.
