The "Patent" razor .......

[randydance062449]

Good morning!,

Todays razor is stamped "Patent" ( I think, )

The scales are handmade, one-piece, very thick, almost 1/4", and the nail as a pivot pin is probably not factory stuff.

The blade had a lot more black stuff on it yesterday before I did some quick work on it.
The spine is rounded.
Does anyone have an idea as to the date range?

1750-1800
1800-1850
1850-1900

Thanks guys,
