Hi Bill. nice pickups. The ball appears to be about c.1930 - a little further research could probably confirm that based on that Winchester box design.
Those early multi-color stitched softballs are not in great demand as a collectible, but I find them to be cool display items, and have a few (pics below).
It is hard to tell from your pics much about the bats. Can you post a full picture of the bats?
The feature that most defines an early indoor baseball bat is that they were much thinner than a regular bat, designed to have a smaller batting surface. I've typically seen them around 32". There were a lot of bats designed for recreational, playground, youth, or indoor use, so it may be hard to ever confirm if your bats were necessarily intended for indoor rules use.
