MO DPO - Delphi CDS and untyped killer in blue

The Delphi Post Office in Gasconade County, Missouri, was one of the earliest postal stations in the region, operating during the mid-19th century before being absorbed into neighboring communities. It was established in 1834, making it the second post office ever created in Gasconade County. The office officially closed or was "transferred" in 1860.
