If you are able to find trees that will fit then you can certainly use them and they don't have to say Gaziano and Girling on the tree. Personally for shoes like Edward Green, John Lobb, and G&G I'll use their branded or Lasted trees but imagine there are many who probably do not if for no other reason than they are fairly expensive. Vass and St Crispins as well but their shoes tend to come with the trees. For me the branded or Lasted trees are part of the whole package and experience.
