What a nice window to history.
I find it interesting is that a quick scan of the list shows, what, a 450-gun range for the SBTs? That kind of volume would have been more appropriate for the early 1920s when the Knick was selling like hotcakes. My take is that Ithaca, like some of the other companies, was beginning to see a lot of their production backing up at the shipping dock. And as Walt points out, some of the guns were just round-tripping back and forth from the factory to the retailers.
As regards the Grand, its attendance had peaked in 1929, just months before the market crash, and thereafter showed a steady decline for the next 5-6 years. By the mid-1930s the Grand was only pulling about half the shooters it did in 1929. I have to presume that a drop in gun sales would preceed an actual drop in shooting.
