Kroehler chest

Looking for a value of a 5 drawer chest from Kroehler. Very good condition with shipping label on the back. Any input would be appreciated.

So reverse google image search has informed me that I've found myself in the posession of a "1960s Kroehler Mid-Century Modern Walnut Highboy Dresser with Rosewood Handles".
While I was cleaning and polishing it up to get ready to use, I noticed (that the Rosewood handles are beautiful but also) that three of the original rivets had been replaced with screws. It's not the biggest of deals, but I'd really like to get it back to the original look if at all possible.
So the question: Where does one source parts (original or reproduction) for something like this? Thankfully I have originals to compare it to, but I somehow doubt that Ace Hardware is just going to magically have three of them laying around. They're flat "rivets" on one side, but the other is a threaded screw that connects to the handle's spacer. Any help is appreciated!
