I have extracted the following entries from the P.O. Directory for 1924/27. This was similar to a telephone book/yellow pages/local who's-who, and was organised in line with postal delivery routes. The first two routes were delivered from Castle Douglas, whilst the remainder are from the Dalbeattie District.
