A.G. Spalding & Bros bats help
 

I've scoured the forum and internet but can't find anything on these A.G. Spalding Bros. bats with the "signature" trademark along with the model numbers. Could someone with more bat knowledge help me out with what I have here age-wise and level of rarity? The lengths are: 150 - 33" 210 - 32" 203 - 33.5"

I don't know what value these retail bats have now, but, back in 1919, the 203's and the 210's used to sell for more than the players' autograph bats.
