I was joshing at the expense of our old buddy Klunkermeister who never lost an opportunity to poop on Model 21s. A poster was referencing a shoot where more than one Model 21 experienced rib separations, implying that the Model 21 was a poor choice for durability. Someone mentioned Klunk in the thread and I jumped on it like a pointer on a bumblebee. Sorry, all my Smiths work today and always have.
