Have a treasured Christmas decoration son made me with an old short 4 oz - 6oz baby food jar. Lid is 2 3/16" in diameter & has been enameled & decorated, but jar it fits on broke. Old lids won't fit on new jars. Old lid is probably Beech Nut, but think Gerber jars where similar. Lids back then had an extra raised area on top just past the edge. Under side had four small bumps that were part of the edge. These bumps made the lid screw on to the jar. Does anyone have one of these vintage glass baby food jars (don't need the lid) that you are willing to part with?
