Broadcast Headphones who made them?
Dear Colleagues.
I just can't find out who made one model of old headphones. In correspondence with specialists from the USA, Australia and Austria, they confirmed that such headphones were not produced in their countries. The inscription Broadcast is in English, I assume that the headphones were made in England. The internal build quality is very solid. Maybe someone saw them somewhere and help me? Maybe you met a logo with two people somewhere? I attach a photos |

Re: Broadcast Headphones who made them?
The script style and logo do not look very English to me but I could be wrong of course. What thread are the fixing screws? There might be a clue there.

A very interesting screw. The size was measured M2.5x3.5. The thread is apparently metric, next to the headphone screw I attached a standard M2.5 screw with a metric thread, the pitch visually coincides. But the screw cap is original. Copper pads are welded onto the steel base of the screw, which form a slot on the screw head.

Re: Broadcast Headphones who made them?
The headphones are similar to some Neufeldt & Kuhnke headphones that I have seen on the internet.
However I have not found that logo anywhere. I spent some time investigating pagan mythology in the hope that I would be able to identify the triagular headed men cartoon. There are many 'divine twins' in mythology, Castor and Pollux, Romulus and Remus, Lel and Polel, etc. The company may be related to Hagenuk and Nordmark. N&K made various models and some were high quality units for the Kriegsmarine. You could compare the internals to the images on the internet (see radiomuseum.org). The Broadcast brand may have been an attempt to market a German made item in the UK when german products were unpopular. |

The internals of the Broadcast headphones are similar to one model of Hagenuk (N&K) headphones, where it was available to see the photo. Although such a design, a horseshoe / arc magnet and two coils could be copied from each other. This is where the similarities end. At the Hagenuk (N&K) company, I did not find any headphones in a duralumin casting case.
