I really like old latches. There are so many different kinds. It seems like, back in the day, people just kept making different styles of things, searching for that better mousetrap. I'm a big fan of construction material recycling.
There's a great one in my town, "Bring Recycling", that moves so much stuff. They have crews that contract to demolish structures and bring the material to their big operation. They were a lot cheaper when they were small and essentially in a mud puddle by the river. But now they have gone upscale - they sell more, in nicer digs, but at higher prices. I have a lot of their stuff, from the old place, lol.
