Silly Billy tried and spent enormous sums of money and he was about 6 short. There are some notched samples of some of the ones you need but I think they are in collections and are not going anywhere. I need about 18 to complete the set but I sold about 5 or 6 to Silly Billy for $100s each many years ago. Ricky P. has some you need for sure as he got Silly Billy's collection after Silly Billy died.
Take care,
Jerry
