Indeed Dave
To support your comment to the masses, here two more examples fro Brooklands
When presented by BAF the Viscount was given their current title (The script type) where in fact she never wore that in service.
G-APIM was, by far, the last to get British titles and didn't have them long but fortunately the recent repaint has seen her now get the most typical titles she wore...also the nicest.
The Vanguard has artwork showing 'ES in FJ pax, a livery that no Merchantman ever wore before conversion
Another classic example is the BOAC Comet 4C at Everett that was originally with Mexicana and the Trident 1C being restored that will be in Northeast livery, not to mention Cosford withe the incorrectly painted BOAC Comet and the Britannia which has lost it's incorrect BOAC livery for a fake RAF paint
Museums tend to be more interested in general popular presentation rather than pure historical fact, like the MAM Viscount that was never Capital or the Science Museums Constellation that was never TWA
