Resin models are made to order so they are “always” in stock.
Etched models may or may not be in stock depending on the number of items etched on each sheet. Most coach side etching are printed 3 to a sheet but there are exceptions. Large pieces, such as full coaches are usually one to a sheet and will mostly generate a “On Back-Order” message, indicating that they will take more than the normal 28 day delivery time.
The images on this site are indicative of the prototypes that the models represent. Manufacturing and materials, especially for printed examples, are constantly evolving so current production may not appear as shown.
