1947 wiring and fuse box still in use.

Had a NG job on a old farmhouse,the main transformer had blown up in the field and course HV to go in the property. The fuse board is currently a wooden wylex and the entire place is wired in a mismatch of mainly black rubber with slightly more modern PVC for a few other bits.They will be having a rewire at some point but for now I need to change the main board interesting to see all this old stuff still in use. This is a sub as it’s a big house proper wooden little box with porcelain fuses must be original
