Barred Letter Obliterators

The Offices and their Barred Letter Obliterators are shown below. The following observations are made here:

the impressions are almost all rough and presumably impressed quickly;

only stamps (no forms) have been located with Barred Letter impressions and all the stamps are of low denomination - up to 3d;

11 bars surround a circle in the centre of diameter 15 mm;

the second top bar and the second lowest bar are both broken by the inner circle. This dose not occur with the duplexes.

the only letters in the impression are those within the circle - so no indication of Telegraph Office or Post Office such as happens with duplexes (see below);

Perth (P)
Albany (AL)	1860-64 printing perf 14.	1890 printing perf 14.
Arthur River (AR) Letters transferred about 5-6 years later given that Arrino had closed in 1880.	1860-64 printing perf 14.
