Ericsson made this model in large numbers and were used and sold around the world from 1895 to 1920s. This is a sought GPO model number 16 and is the post 1912 version. Earlier Ericsson models were used but had their decals painted over and the tear drops removed. This one was manufactured for the GPO and so this is how I can tell it was made post 1912. It is complete and in great un-restored and complete condition. The black plaiting was probably a little shabby and so many years ago someone has removed it. You can see this was done a long time ago as it now has an aged patina to the bare copper. This model is an iconic telephone and a must have for any GPO collector. It is as found and not working and still has its original cords that are over 100 years old. A wonderful item and if you have the time could be restored to perfection. Note even the mouth piece is undamaged and an original one marked No1. A real collectors telephone and a genuine antique telephone. loads of pictures to see and a video. Spent many hour on this listing.
