From the tail and grind, I'd guess 1840's maybe. No idea on the maker, though.

My guess with rough scales like that is they were homemade replacements. There are tons of examples of razors that old with really nice scales, so I cannot imagine anyone would buy one new with scales like that.

Lastly, and this is just a personal pet peeve of mine - that is not a Full Wedge. I can see where the razor has a band of wear at the spine and above the edge. Since they do not meet, the whole razor does not sit on the hone, and it is not a full wedge. Just "wedge" is used more or less interchangeably with "quarter hollow," and I can accept that, but adding on Full should, in quite possibly only my opinion, only be used for an actual full wedge. Otherwise what purpose does adding the word "full" serve. Sorry.... /endrant
