Thx Dave and suchmoon. As nice as some extra money would be nice, it isn't mine and I'd rather it goes back to the owner . Best case scenario the owner does indeed have a copy. Naive question,.. but is it possible with this wallet to identify when it was last transacted upon?
Been back to the beach this morning and nothing else here to help me identify the owner.
Might just sit on it for a bit and seek more feedback. Thanks again. I am very appreciative of your time and advice.
Check the Bitcoin address via blockchain explorer, e.g.:
https://live.blockcypher.com/btc/Put the address in the search box at the top and you should see the transaction history.
Just to add to suchmoon's advice; he's talking about the public address, not private key. Never share or post or upload that private key anywhere. If you do, the coins will be compromised.
As for making a reasonable effort to find the rightful owner; as DaveF said, there are ways to trace the origin of the coins, or at least make the attempt. If the coins originated from an exchange that records customer records they may be able to inform the owner that you have the private key.
If you need help with that there are members here who can assist. I would suggest you stick around for a while, learn and figure out who you can trust to help. Again; never share the private key with anyone, and it's probably best that you don't post the public address in public either.
