It's basically a pinball straight off the arcade room floor.
I'm not a pinball expert but the backglass looks to be in excellent condition. The playfield plastic seems to be in good shape except some heat damage on one bumper cap. I've replaced the rubber bands/rings/etc. The playfield itself has some wear from a lot of active service but it seems to be relatively minor.
Has an Alltek MPU but otherwise seems to be completely original hardware and in good working order. The spinner on left side was missing, I've replaced with one from a different machine but it seems to start awarding "ghost" spinner points every now and then.
