Notes: Web site | Based on magazine ads, the Pitney Bowes mark seems to have been used during the 1950s-1960s, as corroborated by the backstamp. At that time, Pitney Bowes was the best-known manufacturer of postage meters.

The oversized cup on the RimRol WelRoc shape has a dark red or burgundy line intersected by a marquis shaped logo, also in dark red, with intersecting horizontal white lines and a PB in a white circle in the center.
