This original glass oil bottle stands 4.5" tall and has its original box making it a remarkable addition to any Singer collection!  The glass bottles were generally precursors to the metal cans that came with the Singer Featherweights, but they were also used to refill the metal cans in some instances. The bottle is empty and has a paper label in fantastic condition.  We have only seen a couple of these extremely rare original boxes that came from Germany. The box is tan and green on one side and green and tan on the other.
