There's already a chamfer on the other side, but I don't have a tool to make them nicely countersunk so I generally keep them flipped like on the other picture. Let me know if you think flipped are more accurate ... always good to have a second opinion for these things![]()
As for the rest of the real parts ... I never seriously considered it before , but yeah, if you could do it just for three months then maybe it would not be totally impossible for me to collect them over few years I guess.

In my opinion they look better the way you just showed me. Look at the picture I posted of the referance photo. They don't go to a point like the way the airplane washers floating around these parts do. I think fliping them is best, if you wanted to you could use a small file and take your time and make a chamfer but you'd need to be patient. Yes I totally think you could get all the vintage parts in a few years. You'd have to be willing to pay what they are worth. I've learned something about this hobby, eventually everything shows up.
