Used to go out for unusual stuff hauling passenger trains. Had quite a few 20s. Did not particularly do large amount of duff bashing but every Saturday in the summer of 1990 one came through my local station. RfD 47s on passenger trains were quite unusual at the time.
Too early for clues on this one yet.
Ducking the issue there I'm afraid. You know as well as I do that back then when it mattered duff bashing was not something anyone would ever have admitted to. I doubt modern enthusiasts would be able to believe the scorn in which this activity was held, after all, what is the modern equivalent of a duff (although possibly now
everything is a 'duff', and maybe that's why some people these days seem to think there's nothing wrong with liking 'em)? Even the passage of time has not moderated my views on duffs, and I have almost no fond memories of them. And it's not as though I'm some sort of doctrinaire English Electric man, as many duff-haters are: 33s were right up there for me (although the less said about Peaks the better TBF).
