I found an ironrite in a wood cabinet, manual, and over 60 years old. Can you help me with a date?

It has the owners manual that is in good condition. It mentions a date in the front that was in 1919, if I remember correctly. I have never seen one and am very interested in finding out what it is worth. I will take pictures of the labels on it and get them to you if you can tell me when it was built. Please e-mail me at chiefcain@hotmail.com and let me know when the wood cabinets were made. The previous owner may have owned the ironrite for 60 or more years. Thanks. David J. Cain
