Yup, 1910-1920ish basketball, I believe. No air hole, lace-up style. Needed to unlace the ball each time to fill up the rubber bladder on the inside. More than likely the rubber bladder is no good (doesnt hold air anymore) and/or has already been removed and it's been restuffed with something else for display purposes.
Though melon footballs are similar, early ones also had no air hole, and they were much more round than today's footballs, more like a rugby ball. Yes, difficult to get hands arounds and throw, hence the development over the years, but they weren't completely round like this, and didn't have the 6-8 panels. Or at least I've never seen a football with that type of configuration either. But had a couple basketball just like this;) Hope this helps you out Bud!! Take care
