Not sure if the board is original anyway, these machines normally have a Nintendo 3in1 board in them.
Looks like the ctpanels have been changed at sometime in it's working life, they normally have linework on them.
I wouldn't be too worried about de-valueing it, it looks like someone has already messed with it.
Saying that they are a good solid machine and it looks like your crt is good so your on a winnner with a 60in1.
Make a bit of cash back selling the Ladybug board.
You could dress up the ctpanels with a bit of original looking artwork/linework
