from April to July 1931 before the label was discontinued. The first Bluebird records appeared in July 1932 along with identically numbered Electradisk records. Test-marketed at selected Woolworth's stores in New York City, these 8-inch discs are so rare today that some issues may no longer exist at all. They may have sold for as little as 10¢. Bluebird records bore a black-on-medium blue label, Electradisks a blue-on-orange label. The 8-inch series ran from 1800 to 1809, but both labels reappeared later in 1932 as 10-inch discs: Bluebird 1820–1853, continuing to April 1933, and Electradisk 2500–2509 and 1900–2177, continuing to January 1934. Electradisks in the 2500 block were dance-band sides recorded on two days in June 1932. These rare issues were given Victor matrix numbers, but the four-digit matrix numbers on the 78 look more like those found on discs from Crown Records, an independent label that had its own studios, though its products were pressed by Victor. The few records in that block that have been seen resemble Crowns, leading to speculation that all were recorded at Crown. The 2500 series may also have been for sale only in New York City. In May 1933 RCA Victor restarted Bluebird as a 35¢ (3 for $1) general-interest budget record, numbered B-5000 and up, with a new blue-on-beige label (often referred as the "buff" Bluebird, used until 1937 in the US and 1939 in Canada). Most 1800-series material was immediately reissued on the buff label; afterwards it ran concurrently with the Electradisk series (made for Woolworth's). Another short-lived concurrent label was Sunrise, which may have been made for sale by artists or "mom & pop" stores. Few discs, and essentially no information, survive. Sunrise and Electradisk were discontinued early in 1934, leaving Bluebird as RCA's only budget-priced label until RCA Camden was formed. RCA Victor also produced a separate Montgomery Ward label for the Ward stores.
