The organ of San Andrés Huayapam is the last 4´ table organ with religious imagery; carved on the crest are the vessel and sprinkler for dispersing holy water. It was an austere instrument until the 20th century when it was painted a cheerful red (vestiges are still visible), and the façade pipes and religious carving were painted silver. The case was later varnished and darkened with time. The organ was originally located in the choir loft but was later moved down to a side chapel. It has no accessory stops and, unlike most 4´ table organs, sits on one table with the bellows behind. The first octave of the principal rank was specially designed to fit inside the relatively small case. The tallest four pipes were made of wood and stopped, while the following four pipes, open flues, were made of metal and bent at the top at an angle. Therefore, the façade pipes, including some dummies, were shorter and corresponded to the second octave of the principal stop. Organ builders aimed to arrange the pipes and mechanics as efficiently as possible inside the case to avoid the increased expense of a larger case. The layout of this organ reveals a particularly creative solution.
