Vintage Aladdin Cobalt Blue Oil Lamp with Nu-Type B Burner

Vintage Aladdin Cobalt Blue Oil Lamp with Nu-Type B Burner. I bought this lamp at an Estate Sale and therefore I do no know the age of this lamp but it does not appear to be very new & the Burner appears to be used.

The knob that turns the wick up & down appears to be loose but something is stopping it from moving more than a little bit. I have not tried to fix this as I'm not familiar with burners & didn't want to do any damage to it.

Under the bottom & along the edge it just says Aladdin (see pictures). I do not find any nicks, chips, cracks or repairs. The glass font measures to approximately 9" high and the whole lamp, from bottom to the top of the Burner, measures 12 1/2". If you have any questions please don't hesitate to ask.

I'm not always on the computer but will get back to you within 12 hours.
