OP, I'm interesting in your Winchester Model 11 and maybe a few of those Spanish doubles. Even if they aren't shootable I'm always looking for a few wallhangers. I'll even sign a waiver if that makes you feel better.

Send them to a gun buy back.

Sell them to someone who may want to refurbish or is looking for parts for one/ maybe use them as wall art stuff

Give them away

Destroy them as a last option Unlike most people I have no problem destroying a unsafe gun. The last few shotguns I had ( a few side by sides) i ended up giving to my BIL and he turned them into freestanding lamps in his house. And these shotguns were not in any shape to be refurbished. Cracked barrel tips and loose tolerances rust etc. They were just overly used as hunting shotguns for years and years and finally wore out.
I rather give them away than destroy them but if I feel its unsafe to use I rather destroy than give it to someoen who thinks they can use it as a self defense weapon

I could use an old cheap wall hanger for my man cave! Where are you located?

Do this and recycle the parts. Someone may be looking for what you have.
