3" Chiefs are my favorites, a square butt enhances the deal, and stainless steel makes it irresistible.
There's much misinformation floating around about the 1984 Jovino square butts. In one of Dr. Jinks' more informative letters he explains there were 600 2" square butts and they were so popular Jovino asked for a 3" model later in the year. There were 1,000 of those.
According to the Jovino ad of the day, the models were exclusively Jovino offerings.
