I know I'm going to get carp for this post, and I know what I'm asking about is a dangerous bit of kit OK. When I worked for the SWEB in Bath we were issued with Drumond test lamps, and a black, yes here goes a black neon tester, I'm a bit of a anorak as far as old tools are concerned and I can't for the life of me remember the make of them, they were basically black with a screwdriver end and a cap with a clip on the other end, does anyone remember them? if so grateful if you could let me know.
