Pulley ID thread

Here is a rather unusual cast iron small block pulley.

It was found on a 1970 small block & had been added on in front of the stock crankshaft pulley.

It is part of an 'add on' Air Conditioning kit. The name ' RIGIKING ' is cast into it along with the number 9117618 while the paint applied number is 91-17619 ;
