I have a Stanley-Bridges 4-speed drill (1970s) for which I have strong affection as it was given to me by my father. Unfortunately i overloaded it some time ago and popped the thermal cut-out. You can reset this by opening the casing and pushing the slider in, but this works for only a short time before the cut-out pops again. I want to get the drill working properly once more. Does anyone know where I can get spare parts for it? I'd need a new motor complete, or perhaps only a replacement cut-out. I understand that, when Stanley-Bridges folded, they sold all their spares to a man who sold them from his home. Any idea who that was?
