At some time during the first couple of decades of the twentieth century, Manco Mfg. Co. manufactured the "American Sash Trimmer", which had earlier been manufactured by the Heald Machine Co., and by the Mann Corp. of Kankakee, Illinois.
In 1977 Manco was acquired by Peddinghaus Corp.; so far as we can tell, the manufacture of sash trimmers had been discontinued decades earlier.

- OWWMer Tim Jackson provided photographic evidence of his Manco sash trimmer, which is what drew this company to our attention.
- A website, TheFabricator.com, has an article that notes that the Peddinghaus Corp. purchased Manco Manufacturing of Bradley, IL, in 1977.
