As I said, I don't know anything about it other than he said it worked, but I've never been able to test it, so it is being sold'As Is. The inside of the box looks really good, all the padding looks to be intact and there are three removable holders, there is also a chart of some kind on the inside of the door. I did clean the outside of the box when it was given to me last year. The case is in decent shape, it has one bad spot on the rear, it is missing the handle, and the lock. I've never tried to see if the light works. The microscope looks to be in good shape, and all the adjustment knobs seem to work ok. It has a light mounted under the table, the power cord has an on/off switch, but the plug is not a US plug, it has two round prongs on it, I assume it is a German plug. It looks like it has room for 4 lenses on the head. Other than it was originally from Germany and was given to me by my former boss when he moved back to Germany. Up for bid is a Ernst Leitz GmbH Wetzlar microscope with these numbers on the frame 529769 and below that 6650-1.
