This is a big thank you to PaulMc for the photos he put on the forum.
I can confirm that the AutoSparks 10 Way Blade Fuse Box C160 is identical to the three fuse boxes fitted to our Defenders.
The C160 packet consists of the fuse box, a lid, the white push through locking plastic bar, two x 5 way connectors, three x 3 way connectors and twenty x 1 way connectors.

I only wanted a single terminal - but at least I now have some spares!
