There was a painter Frederick Richard Lee 1798-1879 who painted in that style. Evidently he did a lot of paintings unsigned. I cannot imagine that he would have signed just Lee in those days.

Hi Kiffin
I have come across Fredericks works while trawling the Internet and yes it does look remarkably similar but most of his signed paintings that I have managed to view are signed F.R.Lee.
It does look old and it does not smell like new oil paint, it has no smell.
Remove it from the frame and look at the stretcher, reverse side of canvas, fittings, etc. Do the stretcher bars look new? The type of wood used can give an indication of the age. And the type of tacks or whatever used to attached the canvas will also vary according to the age of the painting.
