I have an Aladdin B-87 Rose Moonstone Vertique Oil Lamp with Model B Burner for sale. The lamp itself is in good condition. No cracks or chips were seen. The burner is in good condition also, with some buildup of dirt/tarnish but overall good.
The outer wick tube has a couple of stress cracks in it, which is fairly typical for the model b and can still be used, or replaced. Please see the pictures for more detail, as they are part of the description and may show something that my eyes missed. If you have any questions, please feel free to ask.
Thanks and have a great day!
