Baseball Bat - Metal and Pheneloc

New Old Stock - aluminum baseball bat 4-1/2 inches long, larg diameter 5/8", inner mounting shaft diameter is 3/16", inside shoulder is 5/16",narrow end of bat is 1/2".

The dark material is not rubber, it appears to be a very hard pheneloc resin based product of some sort, held in place with a wrist/split pin almost at the end.

See photos.

Not sure which game this is used on! I believe these are for Chicago Coin, but I could be wrong - John :-#)#
