Enoch & Sons Trios Quartets Female sheet music

We have "Enoch & Sons" Trios, Quartets & Choruses for Female voices. We believe this definitely has some age. It don't say a date on it, but thinking 1950s or earlier. The pages are all loose, but, believe it is complete. It has some writing inside. When counting each side as a page it has 6 pages to it. We have given several pictures of it so please check those out, and if you have any questions please ask.
