Thanks to Robb Stewart for sending copies of this catalog.
This catalog describes the Super trumpet as a new product, and the French Model as a relatively new design. I have documented a French Model trumpet at least as old as 29xx, and a Super at least as old as 41xx. And we know that trumpets were introduced after October 1928. Based on those known facts, I believe this catalog probably is from 1932.
