Lot of 3 Bakelite Top Glass Student Inkwells, All Missing Swing Covers

All 3 have "303" raised on the bottom of the glass and all the glass is in excellent condition with remments of ink in each.  Two of the tops are in good condition but missing the screw on swing cover.  The other top is also missing the cover and has cracks and chips in the bakelite.  Thank you for looking.
