San Andres, Zautla, MEX (IOHIO)
One of two middle-value stamps from the IOHIO set, this shows the organ in San Andres Church in Zautla, Oaxaca. The church dates from the 17th century and the instrument from 1726. The IOHIO site divides organ history in Oaxaca into four periods; this instrument is placed in the first/earliest. The site also reports that there are faces painted on at least some of the facade pipes, making it a polychrome example. The case was restored in 1990 and the rest of the instrument in 1996 by Susan Tattershall. This stamp also has an "error" stamp associated with it. On some copies of the stamp the final "s" is missing for the word "Instrumentos."
Mark Jameson gives this specification of the instrument in his OCJ article. As with many smaller instruments this one has no unison pitch stop; the lowest register is a 4' flute. The single, 45-note, keyboard is divided. There is no pedal division.
