Door latches & hinge piece to ID, please

Hello. I've reached the saturation point in my shop and basement and must start clearing out some things. I've always worried about throwing away vintage car parts which someone else might desperately need. Over the years I have bought boxes of car parts at auctions and estate sales, in order to get one or two items which I really wanted. But that leaves me with unidentified parts like these. Does anyone recognize them at all? Should I just throw them on the scrap metal heap, or what? 

 

Thanks in advance for any help you can offer.
