sorry,
Yes, as far as I know the bag support colour (and the bike) are as the original colour). It looks slightly duller in the photo because the bike is wax polished

, but it's the same shade.
The Scot was restored before I got it, but the guy who did it replicated the factory finish. Red/white with chromed half forks and stays.
It was done professionally (from memory was Mercian) and the only change is that the 531 badge states "531 Frame respray".
The bag support is quite rare and has been brazed repaired at one leg. I've left as is because I think it would be difficult to match the colour again.
