  • Notes
  • This "Soundmirror" model BK-455P from Brush has two tape speeds, 7 1/2" and 3 3/4" per second. Using both channels of the tape the recording time is 1 hour on 5" reel or 2 hous on 7" reel with the slower speed. The company name in 1954 is "Brush Electronics Company" instead of "The Brush Development Company" - the address in Cleveland 14 stays the same.
