Oh yes. I've been watching that one, and was really dismayed by the silly bidding war. Why can't everyone just snipe like civilized people? I was willing to spend $200 on that.

In any event, I did kind of a lot of research on it in the runup to the auction ending.

I found things. Like this:

That is, I believe, a French razor made in the late 1700's. The site I found the pictures on doesn't have a lot of information on it, but of the blades I've seen, that one is most similar. Though clearly the stamp on the blade of the eBay special is different. Looks like "(crown) A -- I"

I found another that has scales more like the ones on eBay.

That one is claimed to be late 1600's, and to have belonged to William 'Pennsylvania' Penn. It probably did, but the pasteboard coffin in that picture looks suspiciously new to me (much like the coffin in the collection of the Mayflower museum).
