In early February of 1938, the Victoria Times reported that vehicles belonging to the Public Works Department would begin to be issued with plates the letters `PW`. This move was intended to address a ``confusion that had arisen```and was part of a trio of new letter combinations introduced that year, including `PN` (for Doctor`s vehicles) and `PF` (for Forestry Department vehicles). It is not clear at which point the use of these types of plates ceased, but it is thought to be in the mid-1940s.
