Lost my Dad this week,
So sorry for your pain and loss of your father. All I have to offer is advice from what I learned a few years ago. DON'T let material items get between a relationship with a loved one, especially your only brother. It's always the one who wasn't around for the tough times who shows up first to collect. Give him whatever he wants, you should pity him, he missed out on the last years of his father's life, you were blessed to be there until the end... that's worth more than material things.
