Seneca Cameras, Seneca Camera Mfg. Co., (Rochester, NY), Catalogue U, undated c. 1920, ~6"x9 ½", 32pp
At thirty-two pages, this is the smallest catalog for years. However, since it contains no view cameras, yet view cameras appear in later catalogs that were featured in earlier catalogs, it would appear that this catalog was not designed to contain the full line. The accompanying letter, dated April 21, 1921, refers to this as their "1921 catalog", yet Catalog T was copyright 1919, so this is probably their latest catalog for April, 1921, but printed in 1920, being only one letter removed from T.
