Just another question of historical interest - does anyone know what the first machine was that incorporated the dummy zero. I know it was different for different companies - Gottlieb probably being last to use it. But what was the first machine?

Thanks Dave - yeah, I meant specifically the score reel dummy zero over in the "1"s column. I just worked on a Bally "4 Queens" this morning, from 1970 which had the dummy reel, and I think there was one Bally from the year before, 1969, that had it as well..."King Rex". That may have been the first Bally to have it - just wondered if Williams or Chicago Coin had one with that dummy zero before that.

Thanks for the link to Army-Navy. Is a "totalizer" just something they called a score reel back then?

Thanks jr and IPDB - I love being able to tap into what folks know around here! I didn't realize those early games had score reels (totalizers). I'll look them up on IPDB and take a gander....thanks!

I thought it would be a clear line of demarcation between machines with a dummy score reel zero at the end and those with all active score reels, but it sounds like it's a little more complicated than that.
