LP14 Aladdin Lamp Clear Glass Base Colonial Marked Model A untested

I will be listing several old lamps. The LP code at the beginning of the title is for my reference only. Expect normal age related usage and wear- see pictures. As I reviewed pictures - I noticed a line - see the last picture - no roughness detected inside or out. Examine all pictures and zoom in.

I do not polish the lamps - I wipe off the dust and dirt but no deep cleaning or polishing.
