Cathi, I did not realize that the #42 cabinet was the only one that had this distinct feature. Neat! It also of course has the pen/pencil tray next to the ink well and the spool/bobbin holder in one of the right hand drawers along with the oil can holder. Does your bakelite lid have any marks on it such as a number or letter or ??? Are these cabinets really that old that they should have an ink well in them? Well, they do so I guess they are!
