How many do you need?
I think I may have some squirrelled away in one of my many boxes of old hardware. I cleaned out my wife's grandfathers cellar many years ago and ended up with a lot of turn of the century bits. Then I cleaned out my fathers junk from his shop and carriage barn and ended up with even more. I also had several early homes with shutters that were held closed by these beauties. I may have accumulated some in my own junk bins.
Before Lowes, junk bins were the source of so many things...screws, nails, eye hooks, you name it.
