The CV287 is a miniature voltage stabiliser and its direct commercial equivalent is the QS150/15.

The striking Voltage is 170 and for burning currents of 2 - 10 mA the regulation is 5 Volts. The electrode at pin 4 is the priming anode and it should draw no more than 500 μA. The data-sheet has more details.
