yup it's a big mess.It looks like a partly completed or damaged [missing components] astable multi-vibrator configuration of the 555 timer. Output pin 3 seems to be driving the base [via a resistor] of a transistor for an unknown purpose. The transistor collector connection is not made to anything external.
IC power pin 8 connection seems to be missing on the underside of the board.
Basically it's a mess.
