I've owned over 60 of these style bats at one time and almost all of the 1912-1925 model Spalding bats had the trade-mark on the knob only. Very few had them on both ends and maybe one or two on the end only. Most of the Gold Medal 1908-1911 line of Spalding autograph bats had the trade-mark on both ends with very few on only one end. I've also kept track of 2-300 bats that have sold in various auctions, ebay and publications. Cy Williams was offered in the 1917-1924 time range. Although none of the Spalding bats are what I consider common this is a bat that turns up semi frequently.
