Amazing condition for the age though not perfect. If you look at the pictures, you will see the clips that hold the top in place are not all there. One side has the top latch but the other latch is broke off, the bottom has one “receiver” for the latch, but the other side is broken off. Please view pictures as any other pieces that may be missing or broken I may not be privy to. All 3 wicks raise and lower via the twist knob.
