Rewiring a lamp - help needed

Hi all
Hoping someone on this forum might know the solution to a problem I'm having rewiring a large Jasba Keramik lamp I have. It's a fat lava lamp with a bulb fitting above and below. I can't work out how to separate the fitting inside the lamp so I can rewire each bulb fitting. Has anybody got any ideas how to do this?
Thanks

I rewired one last year, i'm just trying to remember how it all fitted together. I think there was a brass section that runs top to bottom with the bayonet fixing at each end. If I remember it was a bit tricky and would recommend taking a picture or doing a sketch of the wiring configuration before you strip it completely. Sorry I can't be more help, memories not so good

Cheers Davee. It's a start at least.
