I manage to clear out the remainder of the wheel house fire systems and strange brown wooden box. Makes a big difference to the space. Cleared out much of the fire system wiring. So some progress was made again today. The battery chargers are unshiftable alone. The transformer itself can only just be lifted but not moved and the cabinets are similar. I have no idea how I managed to get them off the wall in the first place.
Introducing Dave. Miracle worker in steel. Thanks for the new hatch Dave!
