Thumb screws for the lower condensers.
The housing twists off once you loosen the thumbscrews.

The upper variable condenser slides right out of the drawer, it's mounted to a metal plate.

The lower ones are loose in there but there is a ribbed foil "spacer" that you want to note its position and replace as you found it.

The rest will need tools like adjustable wrench and pliers and maybe some screw drivers.
Be careful of the negative stage and the lens stage under it.
Like don't lay it down resting on the neg stage etc.
I would only disassemble what is absolutely necessary for transport.
