I found the Fox Transfers set on their website. Bulleidboy is right. Brass name plates with either red or black background, brass doncaster builder's plates, and a steel number board for the smokebox.
Looking to purchase a BR express blue A1 I came across an ex R1172 A1 60154 Bon Accord on ebay. Looking through the pictures I realized this is the steamer from the e-link Majestic set and is missing the deflectors and name plates. Does anyone have any ideas what to do about spares?
