I just picked up a '59 Gottlieb "Sraight Shooter". Around the complete lower cabinet, at the top just up to the top rails, there is a strip about 2 " wode that has a seperate pattern of paint then the rest of the cabinet. This would be the two sides and the front. Ok, so this pattern, the paint is a lot brighter then the rest of the cabinet and has a quite profoud stright line along the horizontal "bottom" of this pattern that makes it look like this game from day one had some sort of material OVER the cabinet. like a strip of metal sort of. so the paint underneath didnt fade like the rest of the cabinet , if this makes sense.
Also right in what looks like this covered area of the cabinet there are screw holes about every 7 inchs.
Di the game actually have some sort of aluminum, steel. or something else that was attached to the cabinet for some sort of curb appeal?
Thanks folks.
Weeze

Well, I NEVER would have guessed that this was the reason. I'm going to have to believe that there was metal installed at one time. The holes on my game do not line up with anything on the play field so I'm going to assume those holes were made to hold the strips on.
Cant believe so many yall knew exactly what was up with this. Thanks for the info, always good to learn something pinball !
