Been to the Museum on many occaisions but have not seen anything related to the fire, I remember seeing some of the telephone equipment at the Fire Section at Boulmer. If you get the chance to visit you will not be disapointed, Dougie Robb has done a fantastic job with the R30 and has also taken on a lot of the Coltishall Museum artifacts as well.
Saw the burnt door (with the scratch marks in it) of the PBX in the fire section at Neatishead back in 1981 during an ATC Camp visit there (and went into the R3 before it was refurbed). I Think the stuff that was in the fire section went to a Fire Service Musuem somewhere.
