Just joined the club! Picked up a nice Mata Hari this afternoon from a friend with a CPR playfield, CPR plastics, and a new main board. The original backglass looks great from what I can tell. Saw and played this same game 5 years ago and really enjoyed it. I asked the seller if he ever went to sell it to let me know!
Still need to find out what model of main board was installed. Seller told me theres dip switch settings on it to change game back and forth between 3 and 5 ball.
