In Reports of Cases argued in the Supreme Court of Ohio there is a case involving the company of Kanmacher and Stark who were employed by the Board of Trustees to build the Ohio and Agricultural and Mechanical College. On 23 Dec 1871 Kanmacher and Stark signed a contract with Dunn and Witt for "the material and labor of the slating, galvanized iron, and tin work necessary in the completion of the building". Kanmacher and Stark failed to pay Dunn and Witt what was owed to them, hence the court case. So I would assume from this that Dunn and Witt were builders specializing in roofing and guttering perhaps.
