old GREIST cast iron gooseneck desk lamp

I honestly don't remember where I got this poor old lamp, which I recently re-discovered in my storage closet at work. Nonetheless, after reattaching its (non original) power cord to the socket safely, it still works just fine -- and who, really, doesn't need *one more* light-up-thing...?? :-) <lol>

It stands roughly 16" tall (depending on how far it is bent over) and its base is roughly 5" x 7". The cast iron base and steel gooseneck seem to have always been painted a very dark green color. (which now looks almost black in normal light) The socket shell (also painted) is brass as is the (rather battered) roughly 6-1/2" shade, which seems to have the remains of some kind of formerly clear (?) finish on its outside, its inside was painted a silver-ish color. The socket is stamped with the BRYANT name, the shade is embossed with the HUBBELL name -- both those firms being longtime manufacturers of a wide variety of 'standard' electrical devices and parts. (and both of which still survive today, I believe)

Cast into the underside of its base is its maker's/model info:

"GREIST LAMPS
MODEL L F. B.
THE GREIST MFG. CO.
NEW HAVEN CONN. U. S. A."

According to info in one of 2 other posts here for "GREIST LAMP" I found with a quick search just now, the company ceased production in 1930 or so. That's all I know about it, not having had time yet for any further research...
