This set is a bit of a mystery at the moment. I have yet to see this set shown or mentioned in any Keystone literature. Did it come with one of the Bowling Alley sets or is it a stand alone item? This set has ten pin wooden pins that are 3.25″ high with a weighted core, nine metal balls and is missing the level. The number of balls seems odd but is there an extra or is it short one?
From my private collection.
