Ex workshop spare parts and small manufacturing stock
ALL devices have been sourced through reputable local distributors such as RS Electronics, Farnell, WES and Rockby (Victoria) NOT direct import Chinese (often dodgy spec) devices
The heritage of these devices is a bit vague, while I am familiar with the "stock standard" manufacturers logo's, this device has a logo which looks very much like that used by Thompson years ago.
I have tried to capture a photograph of the logo from the devices but my camera is very "old school" and just cannot cope with such small images. Instead I have found an online photograph with exactly the same manufacturers logo ...
