Just to add some additional information -
Chassis #3016 was possibly built up from the first #3007 crashed by Nuvolari with the remains being sold to Minozzi and/or Soffietti.
Then modified/rebodied by Mulliner in 1935.
Owners were possibly Whitney Straight, Minozzi/Soffietti, Madame Braillard and later Lippai Fanos of Hungary.
The information may not be 100% correct but is worth adding if anyone discusses it further.
