I agree with Kevin's analysis.. Decal bats appeared after the first endorsement signing on 9/1/1905 (Honus Wagner) during the 1897-1911 label period, so this bat would reasonably date between 1905-1911. Just to add a little to the post, Wagner's earliest records (1911-1912). document orders of bats weighing between 44 ounces and 50 ounces. No additional information is available from that period, Additionally, the Honus Wagner display bat from the Louisville Slugger museum is referenced as 34 1/2 inches and 38 ounces.

Good Luck in future collecting.
