You may know this already, your game is a "Diamond Plate" playfield. That's a great find!
I own a nice PS, that I've owned for many years. I purchased another one locally a short while back and swapped a couple parts onto my PS. The guy who purchased it called later that evening and said; "did i know the game I bought (sold him) was a diamond plate". I said no, and told him he got a great buy and a diamond plate too. I never even noticed
I also did that with an early production (promo?) IJ pinball, with metal mini playfield rails, 3 extra lights in speaker display and red light boards. That was early in my collecting days (live & learn).
