The problem with Reyrolle was too good a quality. They made a switchgear called L42 and it is still working after pre WWII manufacture. Maybe Colin Mc Allister out in Australia will verify that Reyrolle OYT has run across wide open spaces for decades. I think the move to Rolls Royce was a bad one because the high quality in RR Nuclear alone priced them out of orders. Sad really....
