Beautiful Vintage Ruby Flashed Zippered Loop Oil Lamp

This is a lovely small or miniature oil lamp in the zippered loop pattern, that is ruby flashed. It may be made by Imperial Glass Company, as that is the only company I have been able to find with this design, however the mark on the bottom looks like a cross, or maybe a candle. I am not sure. It has pretty much all of the original flashing. It measures 7 inches tall and 3.5 inches in diameter. This is probably antique and surely vintage. It does not have the stack. I do not know if the works are original to it.
