Quoted from Joydivision:CPR didn't do the Fireball repro sets that were available a few years ago, they were done by someone else, They were also screened on thinner plastic than originals. Action pinball used to stock them as well, but have sold out now.
Hopefully CPR will do them though.
And I thought they were the Fireball Classic plastics. Not sure they're 100% the same as the fireball 72 ones, are they?
