Incidentally, just for info, I might point out that 3223 on the DCDR is in 1950s railcar livery. The darker green, on loco hauled coaches, was done away with about 1955, and would have had the broader light green stripes both above and below the windows; these, plus "flying snails", being edged in gold. For the lining style and unlined snail currently carried, only the lighter green, as seen on the TPO, G611 and C231 was used.
For purists, the fonts used on all three G class, both E's, and A39 are correct. That used on C231 is not. The numerals are too thick - see A39 - and the "3" isn't the right shape.
NO ill reflection, none at all, on the SUPERB work of ITG and DCDR people in restoring her. I think the lettering was added to her when over in England.
