The box is Northern Electric most likely 20s to 40s .These were built for use . Real wood and brass instead of the decorator sets with plastic and fake wood cabnets.

QuoteAs for re-soldering the magnet wire to the ringer leads, while I was given credit for the tip, the credit really goes to Jeff Lamb, ktownphoneco, who made me aware of this when I had a 600 subset type ringer that was dead. As he explained to me, to save time when first made by WE, the magnet wire was just cut and soldered to the ringer wire. To save assembly time, the sides of the magnet wire were not stripped of their varnish or enamel so that only the end cross section of the very thin wire would bond to the solder, make the joint. Over time, with temperature changes, the magnet wire within the solder joint would shrink in length and after time could cause that very small cross section of the magnet wire to break free from the solder leaving the magnet wire inside of the varnish or enamel coating tube insulating it from the solder. Re-soldering such a joint would again bond the magnet wire with the solder and the ringer wire creating a near resistance free circuit.
