The ink wells are clean and the unit looks like it was well cared for. As you can see in the video the unit runs but I have not put any ink in it and I have no idea how to do anything with it other than it turning it on. Comes with everything pictured, would make a good conversation piece. Make up a story about who it was used on, mobsters, murderers, clowns  Good luck bidding   Place a Bid!
