ATEA phone from the 20s. In this period ATEA was part of Automatic Electric (Strowger). It is therefor no coincidence that this telephone is based on the Automatic Electric Monophone.
Although this is an autonomous telephone, it does not contain a signaling device. A seperate ringerbox is needed for this telephone.
The handset is a typical ATEA design. Already patented in the 20s, you can find this model, with minor adaptations, on ATEA telephones well into the 1960s.
This is a very rare telephone, nowadays.
Interesting AE/European hybrid. Based on the non-dial AE Monophone (as opposed to the dial 1A Monophone), then a dial mount was apparently added to the exterior. And it’s got an AE number card, too. I wonder what the ATEA subsets for this model looked like
Thank you, Dave. It does not really need a subset. It is an autonomous phone, with all the parts inside: coil, capacitor etc. In only needs a ringer. Not sure which model, at this time. I think it is the ones with the gongs on the underside, the upside down model.
