Personally this razor screams Sheffield to me, 1830-1860. I believed this razor was made by Joel Rose of Sheffield, Joel is listed as a cutlery manufacturer in 1833 in the Directory of Sheffield, and later as Joel Rose and Co, Pen & pocket Knifes and cutlery distributor in 1837 in the same directory.

Like Engine46 mentioned it is more the probable that Joel was a descendant of John Rose Jr & Joseph Rose of Wadsley since Joel is mentioned in some directories from that region as well. The dating seems right for this razor.
