I found an Ernie McCracken ball from Kingpin (1996)

It wasn't likely an official prop, but it was fun to find.

Kingpin is such a weird movie, but it worked. Super silly & over the top.

The synopsis for those who haven't seen it:

Roy Munson (Woody Harrelson) is a young bowler with a promising career ahead of him until a disreputable colleague, Ernie McCracken (Bill Murray), tricks him into participating in a con game that ends with Roy's bowling hand crippled for life. Years later, Roy discovers Amish bowling phenom Ishmael (Randy Quaid), and plots to take "Ish" to the top of the bowling world.

"They don't make movies like that anymore!"
