As a buyer of a ball bowler, its always best to assume it needs a full mechanical restoration, UNLESS you can play a full 6 player game. Every ball bowler I've bought the seller stated it was working before being sidelined, and of course it just needed to have the contacts cleaned. Each & every one needed all sorts of work.

As a seller of a ball bowler, unless you can present buyers with an operational machine, you're just blowing smoke.

Cosmetically, this bowler needs lots of work. Lots! The upper/lower backglass appear to be fairly good.

Pluses of this ball bowler. Its a 16 1/2' bowler. The big one. The switches, score motor & steppers look reasonably clean. Formica is dirty but appears it will clean up reasonbly good.

Minuses of this ball bowler. Unknown mechanical condition. Needs substancial cosmetic attention.

My $.02 worth opinion on worth. $400 - $700 Maybe go a bit higher if you really really want a big ball bowler.
