systemdek, sumiko arm, ??? cartridge

hi,
I have a systemdek IIx table with some arm with "Profile" in white letters on it. The arm is straight and I think it is a Sumiko; any information appreciated on if I am correct (or if not) and how to set it up.

Also, there is a cartridge with "bx150e" printed in white letters. The housing is shiny black plastic but I cannot find any MFR name. It does not appear that the stylus can be removed but I am not 100% certain.

Any input is appreciated.
