I have for sale an original 19th century Boston & Sandwich glass oil lamp. Overall, the lamp is in very good condition. The only thing I notice can be seen in the (15th) photo above and more below. I believe that is a slit like imperfection in the clambroth glass and not a small crack. I have provided additional enlarged photos below to give you a better view.
The clear and opaque etched shade is very good condition with just a couple very minor fleabites around the inside rim. I have provided (100) photos below in the listing to give you an incredibly thorough view of this rare Sandwich Glass oil lamp. Total Height 21 1/2" (Shade Height) 13 1/2" (Height to Top of Font). The burner is patented March 10, 1868 & May 6th, 1873.
I love the way the orange paint on the font goes with the blue on the base. If you have any questions, and/or need more photos, please send me a message.
