My husband is about to inherit about 50 guns, where do I draw the line? Or should I?

He is going to get about 50 guns from his father and expected to keep them forever and p them down. He is not supposed to get rid of any of them, not sell or give away. Some of them are important, a couple from the civil war etc. I don't have a problem with those. The other ones that aren't worth much and not significant I don't think we should be expected to keep. We rent a house and do not own a gun safe, so we will have to buy one, a BIG one. I find this to be a big burden, but my husband does not. I would never p down that much stuff, I would not want to burden someone with my collections unless is was truly significant to the family, like an heirloom. My husband doesn't want to dishonor his dad and will just do whatever he wants. Ugh, very frustrating.
