Hi all this is my first time on this site and i was wondering if anyone can help me out by identifying some cannon ammo i have. an old man gave them to me about 8 years ago when i was fitting his windows.. forgot i had them now i just found them and two of the shells look pretty much live to me. should i get them out the house quick or am i safe. allso would you know if they have any value to them as i would be looking to sell if anyone interested. thanks.
