If I had a spot to fire it I certainly would!
I have a friend here who built his own, very much like yours. He has many photos from the 60s through 70s where it had been in plays (even a local high school play, where he actually fired it, in the auditorium!).
He tells stories of rolling down to the corner, where he still lives, and firing live ball down the dirt road (now an occupied neighborhood), he said all the neighbors would come out and cheer. Life was grand, back then.
Today even some local historic sites that used to have him come and fire no longer allow him to, he can bring it, people can look at it and touch it, but he Can Not fire it...
Today it sits in his garage, his dog recently died, his mind is slowly digressing so he sits, and in his mind; life was Grand, back then.
...sorry, cannons just make me think of him...I think the wife and i will pay him a visit before the new year, I'm sure he quite knew who we were last time we stopped in.
