These are some photographs of the Burndept BE525 acquired by Dave G8EPR, curator of the Pye Telecoms Museum.
These sets are marked Home Office and were said to have been used by a Fire Brigade but it is believed that they must have been used by the Royal Observer Corps because of the numbering and frequencies of the three channels fitted.
Sorry about the quality of the pictures, I will try and get some better ones later in the year.
Better pictures here
A number of people are looking for BE525's
to use in restoring Royal
Observer Corps posts. Please contact me
if you know of any BE525's looking for a good home.
