O2 Sensor type?

[me]

I have aquired an O2 sensor from a manufacturer's test
bench and cannot source any data on it .  I would appreciate
any-one pointing me in the right direction as to the type ,
manufacturer ,  or specs. on this unit .  I wish to use it as
an A/F meter so I need reliable information . The unit is
a six wire device with csOoo JAPAN on the body and the
numbers 1830  1183  on the hexagon .  

Thanking You ,
