These three rolls of wire can be used for a variety of projects. I do not know the wire gauge nor how much is on each roll. That said they are all very heavy meaning they might cost a bit to ship. So this wire was used to make relays, coils (when coupled with capacitors) make tuned circuits at a given frequency for radios of yester-year. You can also use them to make transformers, or if you are want a really interesting project they can be used to make a Van de Graaff generator or some other ultra high voltage project. I would consider selling each one separately. This item was part my Dad’s estate from many years ago. Pre owned, in new condition. Sold as is, no refunds. Curbside pickup is preferable. If requesting shipment a charge will be applied for packing, and shipping. I will need to price through Canada Post. The QTH is Braeside which is 30 minutes North/West of Ottawa. Cash preferable, or cheque.
