FamilySearch has many of these on microfilm and digitized, but there's a volume (vol. I) of Appraisements and Sales that was not microfilmed, covering about 1852-1858. Looking at what is at the state archives, it looks like they have the same 4 microfilms as FamilySearch, though I've sent a request to archives staff to be sure. I spoke with the Pulaski County Probate Judge who says he does not know where these old records are, that they were moved when the courthouse was renovated and the county supposedly has them safely stored somewhere, he just doesn't know where. Does anyone have any additional information on this?
