Letter from Weinstein, Arnold & Louchheim, St. Louis, Missouri to Eagle & Phenix Mills dated May 4, 1883. The letterhead states that they were manufacturers of jeans and staple clothing. This is pretty much all I know about the company. I've looked in St. Louis business directories from the later 1880s and have found no mention of the company. I did find an Arnold, Louchheim Company that also went by the name ALCO listed in several publications from the early 1900s. I'm not sure if this is what became of the company.
