Match the detail to the prototype

Horn arrangements, mounting points and other fittings vary between locomotives and releases. Check the stated scale, dimensions, material and package quantity on the selected listing. Review whether the part needs drilling, attachment or painting before fitting it; a detail part is not a complete locomotive or a universal replacement.
