You can always do what my sister did when she found a couple of really old irons, one was the type you set on the stove and the other had a little fuel container on the side in the attic. She brought them down when the parents were distracted and put them in her car. Took them home, got them all cleaned up and set up in her family room. Looks great.
Mom noticed them the next time she visited but liked how they had a place of honor in her house and let her keep them.
So maybe convince your Dad that you'll take care of them and love them and always think of him when you look at them sitting in your house.
