Its hard to tell a lot from the pictures but as far as age, its 1920's unless there is a powerized logo.

I wouldn't call them lathe marks on the bat. On the knob, you see the remnants of the lathe nub that wasn't fully flattened and the top looks more like a hole in the bat. Is it leaded or corked?

I don't think the bat is cut down, so maybe the lack of inch marks is due to it being a junior size even though its not marked as such. The 40brj and 40tcj bats that are about the same length are rarely seen with inch marks.

Its a cool bat, could be cleaned up if you want to go that route.
