Oberholtzer, David (2017). Canada’s Barrel Handstamp Cancels.

Barrel Cancel handstamps were used from early 1955 to the end of 1962. Assigned to 34 of the largest post offices in Canada, they were intended for use on mail items requiring special handling such as parcels, registered mail, redirected letters and First Day Covers, among other applications. The main reason they were acquired form the Pitney Bowes Company because they did not require removal and replacement of the date and time indicia, which were mounted in the body of the devise in the form of a barrel assembly. The 1955 hammers were recalled the end of that year because of design flaws, but were replaced in January 1956 with a new model. On many colourful covers and pieces, David Oberholtzer’s exhibit shows how the “barrels” were used in the period.David Oberholtzer has collected stamps since the age of twelve.
