    As an aside one read Mr Powells book recently in which he suggests the Rebuilt Scot / Jubilee / Patriot smoke deflectors were nice looking but not particularly effective - it doesn't take a genius to see why.

    On the LMS the shape of the smoke deflectors mirrored that of the firebox: the Original Scots and Baby Scots had vertical firebox sides and the deflectors followed suit (after some experimentation with the top edge); the Pacifics had sloping firebox sides and so did the deflectors. The Scots and their sisters had the double bend to the firebox sides, and this was reflected in their smoke deflectors.

    Smoke deflectors were not fitted on a whim but to answer a need. The Parallel boilered Scots in particular went through several experiments for smoke lifting before settling on the side deflectors actually fitted. The Big Lizzies, like their earlier sisters, didn't need them in single chimney form, but did so once the double chimneys were fitted.

    As to the Big Lizzies' appearance with and without, it's all down to the individual, but it is true that their appearance was very much altered once they were added.

    The Irish versions of the Maunsell moguls never received smoke deflectors. The only Irish locos I'm aware of which did were the GNRI VS class 4-4-0's (the later and unfortunately extinct 'simple' version of surviving V class compound No.85 'Merlin'), plus one solitary GSR '400' class 4-6-0 (No.409).

    BFB wheels aside, I always think the rebuilt Bulleid pacifics, especially the MNs, look decidedly LMS-ish when shorn of their deflectors. Must be that humongous firebox!
