From memory that looks right but it's been a couple of years since I shopped mine out. Too lazy to get out of bed and look right now but I'll take a peek in the morning.

Yes the gap is supposed to be there just adds something to shoot for when the drops are down. It looks like you have it right compared to mine which I believe to have had the original rings on it when I got it. Got mine and the Al's garage band which I believe you own now from an old collector and I don't think he ever shopped either of them out and he bought both new or fairly close to new.

Doesn't happen often because the drops reset but pretty sure my game says "well done" when you make that shot. Now I need to go play and pay attention to that. I'm more of a casual player so only going off things I've for some reason kept in memory.

Ok game says "nice shot" and awards 2 million points the first time and increases by 1 million for each time after. Seemed like the 3 bottom drops would stay down until I hit the center one of the top 3. It will also start a mode if the rt ramp is lit for it as well, wouldn't doubt it would score a jackpot if lit but didn't check that.
Anyway cool feature that I'm sure was intended.
