Episode 362 - 1977 Williams Liberty Bell

I missed one machine from the bicentennial - Liberty Bell is almost a carbon copy of Williams' own Grand Prix.
Earning a special requires advancing the starts four times, then dropping all four drop targets.  Tough!
The spinners have rockets screened on them, to represent "the rockets' red glare".
