Help with dating 4 older bats - Spalding, Axletree ring, etc

[vintagesportflips]

Hey guys,
My dad picked up these bats recently, the 3 larger bats in a group, and the smaller reach bat by itself, and was curious if you could help me with dating of them. I believe the Axletree bat to be circa 1890s but I could be wrong, and I don't really have much of a clue on dating the other 3. Also, if anyone can point me towards a good resource for dating bats, that would be awesome as well.

The 4 bats are:
1. A Spalding Axletree ring bat with No O. X. below the Spalding mark. The bat is 35 inches long, has lathe marks, and is in very nice shape except for the very faded rings. There are 2 rings evident at the end of the bat.

2. A Spalding Model 200 bat. This bat is just a hair under 35 inches long, and has the Spalding trademark on both the knob and barrel end.

3. A Hillerich & Bradsby Co Bing-Go No 20 bat, with Louisville BingGo in cursive towards the barrel. The bat is a hair under 35 inches long.

4. A Reach bat with lathe marks that is a smaller bat measuring about 25 inches long. The bat is marked with AJ Reach Co - 87.

Any help would be appreciated.
