Ever see a fuse box like this?

Ive seen several aftermarket wiring kits and associated fuse boxes but never one quite this.....ummmm.....basic?

Anyone have an idea of the source?  Its in a CJ5

Looks like Eastern Beaver has something similar.

I bet the one in a Samurai looks similar under all the plastic, minus the relay which was apparently an exotic piece of technology for that era.

I like it.  Nice and simple.  There's probably a brand name on it somewhere, maybe on the back side.

Those are more complicated than ones in a couple cars I have. Has more fuses than my cars. To compound matters, one uses European fuses and the other uses glass tube. I thought my Opel GT had simple electronic system until I got an early MKI Midget. I refer to that car as having a top notch electrical system for 1930 in a 1960's car.

Somewhere in the shop I have a panel very similar to the one in the OP I took out of someone's car I was rebuilding. Half of it is burnt.

My biggest concern is the lack of any protection.  Being it lives in an open top Jeep I would like to see some guarding against the elements.  But it works fine so no need to change it, maybe I will make some sort of cover out of a Tupperware bowl.
