Quoted from PoMC:From what I recall when I had my BSD, there were two types of PFs and one was susceptible to planking. Mine had the one susceptible, but didn't have any planking.
Yes, Sun Process and Lenc Smyth (sp?) were the two companies making playfields for BSD and I believe also CFTBL and a few others. They are stamped on the playfield surface under where the left rule card goes, so you can see it through the apron. LS or SP. The SP ones are commonly believed to be superior to the LS ones.
