Model horse showing is a hobby built around the collection of scale model horses, with equal focus on honouring the (real) horse show industry as well as the artistic merit of the miniatures. Classes & Divisions Model horse shows consist primarily of two divisions: Halter and Performance. There are both Halter-only and Performance-only shows, though many larger shows will include both. Often there are up to three shows run side-by-side: Youth, Novice and/or Open. Individual shows will make their own guidelines for what qualifies entry to each of these categories. Several abbreviations commonly occur: OF (Original Finish), CM (Custom) and AR (Artist Resin). Halter Division These classes evaluate how a model represents the actual breed of horse. The divisions and judging criteria are derived from their real-life counterparts. Although known as "Halter", no tack or costume is required on the model, and it is generally omitted. Halter can be further broken down into subdivisions based on manufacturing medium to equalize the different fields of craftsmanship. Common subdivisions include: OF Plastic or Original Finish Plastic, refers to the original plastic horses produced by companies such as the Breyer Horse Company or the Peter Stone Company. Many shows now further break this down to give separate classes to Breyer and Peter Stone Company horses. OF China/Resin or Original Finish Chinas and Resins, refers to professionally produced porcelain horses produced by companies such as Animal Artistry, Pour Horse Pottery, or Alchemy Fine China. Artist Resin refers to professionally produced resin models which have been individually painted by professional or amateur artists. CM Plastic typically refers to OF Plastic horses that have been repainted, haired, or resculpted, regardless of original material or manufacturer. The custom may be a drastic custom, where the original model is no longer recognisable, or a minimal custom. CM China or Custom Glazed Chinas, refers to professionally produced porcelain horses that have been individually re-glazed, whether by a professional or amateur. Collectibility Division These classes evaluate the rarity and condition of models. Documentation as to why a given model is collectible (i.e. very low number produced, very hard to find due to age, unrealistic colours etc.) is often presented with the entry. Some shows require documentation. Many collectibility divisions also include classes for non-equine models. Models in this division are always Original Finish models. Workmanship Division These classes evaluate the finishwork of the model. Preparation work on the model before
