Very simple design, Variac and a high voltage step up transformer, a few resistors and AC voltmeter, I was able to repair and restore this one, and also super fine calibrate the voltmeter, It was be a good adition to my power supply collection. The vintage tube at the end is called Crookes tube with a flipable maltese cross inside, thanks again :-)
Any info on Willy Nielsen ? the company ? other products ?
