Hi Manager,
Yoda is quite correct, although the driving band shows the shell to have been fired and the fuze appears to be in as new condition and possibly from another projectile that is no guarantee of the likely hood of it being inert. As any member of EOD will tell you if you can't see into it then treat it as live. There are procedures in place to deal with this sort of thing if you have any doubts about anything you come across. I will attach these below for you. Not worth risking anything for a lump of metal however good it may seem at the time.
Reporting live ordnance
Within the UK we have a system in place for reporting suspect items of Ordnance, wether dug up, found, in a collection or shop etc etc.
First of all, contact the Police, they will put in place a system to have the item removed or destroyed by an EOD team that are always on 24/7 standby for the public safety (its their job, so dont be sorry).
In the event of it being free from explosive they do have the jurisdiction to hand back to you as it is your property and not theirs unless it has explosive inside (or unless you have stolen it).
Don't worry about speaking with the Police, rather you be safe than loosing parts of your body and it gives them something different to deal with. They will not arrest you (normally) or put you in court unless you are doing something very dodgy / terrorism / working outside normal rules of FAC and/or explosive handling, producing something nasty, have a launch mechanism for a missile (please check home office guidance or police guidelines).
The above is for UK but other countries will have similar procedures in place
Best regards Weasel
