I have two 1960's Wylex boards, (1 x 6 way for the power and 1 x 4 way for the lighting), they are built like tanks and, I wouldn't change them for the world, (maybe for a new Jaguar perhaps?)!!
I'm ok for the power side, even have some spares BUT, I need 4 x 5 amp MCB's for the lighting, as they are all BS3036's so, the question is... do any modern MCB's fit the old type CCUs'?
The annoying thing is... I know my son throws loads of these away, (as he's doing CCU changes all the time!!), and I have asked him to save some for me BUT, you know what kids are like????
