I bought a 12 lb Bormann fuzed ball, minus the fuze, from Gettysburg ( back before there became a premium for Gettysburg items ) when I was 12 years old, for $12. That was almost 49 years ago - still got it ! Plus a few hundred more now....
Also, bought a Merrill carbine for $12.50 back then at an antique shop.... still got it ! They had a barrell of guns, and a barrel of swords. I bought the carbine, cause at 12 years old, it fit me to play with. I can only imagine what might have been in those barrels ....
First shell I ever dug was a 200 lb Parrott with a friend here on the forums. Quite a way to start digging shells !
