Long story short: I've never been interested in Deltics as I missed them when I was spotting, and they were all withdrawn before the setting for my layout, and didn't do charters until after my layout is set. But I have ordered 55005 anyhow... If I wanted to order another one to renumber, what do I need to worry about detail wise? I see it's got double windscreen wipers, and a quick look on Flickr suggests that 55004/18/21 where also fitted with these in 1981. I quite fancy 55021 ... But what else do I need to worry about?
Longer story: I've decided to be a bit more flexible with the history around my layout, and if I bring the asbestos related shortage of DMUS from the late 80's forward to my timeframe (1983), and delay the introduction of HSTs on the Midland Mainline by a year or two, so the peaks weren't released for trans Pennines services, I could probably stretch reality a little to say that handful of Deltics were kept on (with donor parts from the withdrawn ones) to supply this route, along with generator 47s. (Now Bachmann a generator 47 with plated/sealed headcode panels and no high intensity light please...)
Thanks in advance
