ECN Forum Forums Photo Discussion Forums Electrical Nostalgia What did this test?

Hi Guys,
This is a bit of a toss up as to where to post this.
Should this be here or in the Photo's For Discussion?.
Anyway, here we go.
This unit is a Multi-Amp Tool Tester, built in Dallas (TX?) and was originally used on 120V gear.
A mate of mine bought this and was wondering of it's lineage.
Anyhow, here are the pics:









Can anyone shed any light on this tester?.
I'm more or less guessing that it is some sort of Portable Appliance Tester (PAT), I could be wrong though.
Your thoughts?.
