Fuses protect again current so that's the rating you're most interested in. The slow blow or fast blow is about how the fuse can handle momentary surges, usually when things power on such as capacitors in power supplies which momentarily draw a ton of current.
I think for older cars you use fast blow as has been mentioned.

It took me two days but then I remembered a Forum discussion sometime back on the Fuse Wire to be used in the Lucas CF1 cutout- I commented that standard house lighting fuse wire (8 amp in Australia) could be used in place of the nicely cut aluminium fuses originally fitted. These are nominally for a 240 volt circuit but of course this has no effect on the suitability for 6 volt use.
The saloon still has three originals in place !
