FWIW, someone is making a book about Norm's skullshifter knobs... aka Normskulls, and it's supposed to be sold this fall

I read that Norm sold these in a Crown Royal bag

 

Rumpsville will offer a 60 page hard bound book featuring a photographic collection of over 200 uniquely hand carved wooden skull themed sculptures produced by Norm Grabowski between 2000-2010

by the way, I never saw this until now, his Henway was featured on the cover of the March 1974 issue of Rod & Custom magazine.
