kerosene lamps

[kingsphoto]

I received a give of 5 kerosene lamps, one is green color with a handle,  the rest are a red color, cranberry I guess,.  All have the flat wick.  One has a name called Dorset P&A, Thomason Conn; The other reds say Eagle on the brass top.  All tops are flip.  Does anyone know the history?  I don't expect them to be old, the green one is clearly pressed glass, vintage, bu in large letters says made in hong kong. :-D).  I would liek to know a bit of history though.
