kTest Record
kk
  Before commercial production of any 78 rpm
gramophone-record, the songs  had  to  pass 
through  a  quality  test  subject  to authority's 
approval. For this official procedure there was 
a practice of issueing a single copy of special 
  record, commonly known as   "Test Record".
These records were generally single sided and 
did not bear any printed label of any company
but a normal  white  label  with  hand  written 
information  related  to  that  particular  song, 
  singer, matrix, recording date etc.  If  a  song 
would get approval for  commercial  release,
the white label would rubber stamped "OK"/
"Passed", else "Cancelled"/"Rejected". These
records have a historical importance related to 
many authentic documents  related to Bengali
Gramophone-songs.
