Not if you have a Del Morino. After looking through their 1950s era catalog without any prices, I called to ask about Del Morino. The woman I spoke with had never heard of the brand.
By the way, if you need a complete set of hammer blades for a Del Morino you'd better be prepared to spend $720, and that's before shipping costs are added on. And that's cheap compared to Courtney's price at GoodWorksTractors. He's asking $1,105 for a set of 24 hammer blades.
