You did fine. It’s in good shape. The wear at the kick out hole is typical and yours is less worn than many. It will clean up really well. Beware, this game is decivingly devilish in terms of a rule set for such a game from this era, and it will suck you in. The rule set is fairly ingenious and there is not a single wasted shot in the game, it’s balanced and asymmetrical and has a ton of variety going for it.
It’s never leaving my collection and everyone who plays the game loves it- especially people who like pinball.
Congrats on a great score.
