Interesting! That's a Fischer Skyhawk from 1977, it's a home model (non-commercial, doesn't take coins to play) that apparently was their only pinball offering though there are mentions of a slightly different version of the same game, with only 2 pop bumpers instead of 3 and some minor differences in the artwork. Yours having the 3 pop bumpers I guess makes it the Skyhawk II. Fischer / Questor apparently was in the pool table business and decided they'd offer a home model pin.

All that aside, it's outside of the group of machines I'm really interested in (mostly late 70's-mid 80's commercial machines by Williams) so I wouldn't be a player on this one. It's a neat piece of history, though!
