Question related to this topic please; What coaches and in what liveries would be hauled by a blue as built Merchant Navy, bearing in mind we are talking about a short period; Feb 1949-May 1951. To early for BR green Mk 1s so presumably Bulleid's or Maunsell's, But what livery? Loco I'm specifically talking about is the new GF East Asiatic Company in N gauge. Any help would be appreciated as I'm getting confused! Thank you
