Need help to date this ball

[ScottR81]

So I just picked up a great vintage ball signed by the Cubs Charlie Grimm, Kiki Cuyler, and the one the only Hack Wilson!!

Wondering if someone can narrow down the year this ball was produced or used possibly. I know these 3 played together about 1928-30.

Any info on the ball would be greatly appreciated, thanks!

If you're going to ask that type of question, please post better photos.

Sorry, hope these are better..

these are photos from the dealer I purchased it from, I don't have the ball in my possession yet so these are the best photo's I have of the markings on the ball.

But I figured it out myself, definitely a 1928-30 national practice goldsmith baseball.
