Plats filed in equity proceedings, some of which were placed in the case files, with others being recorded in equity record books. The series consists of plats removed from the case files because of their size or physical condition and placed in oversize storage and of plats recorded in equity records. The Land Office filmed the plats from equity records in 1948, now found in series CM1406 and CM1407. Access available in electronic form, derived from (Plats on Microfilm, CH) in series S1536.
