60's/ 70's Lava Lamp Passed down to me, Crestworth Princess, Help?

[Amy]

Hiya, apologies in advance as i am new to this. I have had a very old lava lamp passed down to me & it is 42" in height, 32" globe & 8+ a half" diameter with red liquid wax & pure copper base (covered in material, maybe later?) & pure copper trim. I have been informed that it is very likely to be a crestworth princess globe but still coonfused about the base as it looks original to the lamp & you can tell the copper is same age as rest of lamp but has later rewiring on it & maybe material covering?

Anyone have any ideas to what this lamp could be & solve this ongoing mystery as its driving me nutz now. If it helps, my distant family were german & it was passed down from this side of the family. Any help would be greatly appreciated. Also any idea of value of it or if it was a princess globe on a diff base etc please?

thanks. Amy
