IF the PVC is in good condition, it may be safe, in the sense that there is no immediate danger.
I'm assuming no smashed fittings, burnt lamp holders or exposed red/black cores.
It is not compliant with current regs, but changing the VOELCB to an RCD may be enough. to 'make it so' apart from one issue.
You have spent some time describing the fusing arrangements, but ceramic and wood are a lot less flammable than the plastic CUs of which a great many are in service
even if deprecated today. I am not convinced of any great immediate danger from this description.
