I checked with my father who worked for BR in the 1960 s and he advised that the TOPS list never had a class 80 He wasn t sure about class 41 however Yes class 34 was originally assigned to the latter class 33 1 as well class 30 was for the latter 31 0 and 72 for the 73 0 Obviously the list was revised at some point but I would agree that it would appear that assigning class 80 to E2001 is speculation 198 134 2 62
