The 6c Small queen was printed using three plates.

Plate 1 had a Type IV imprint(Montreal & Ottawa), and a shaded counter at the left.
It had a single pane of 100 subjects.

Plate 2 had a Type IV imprint with an 'A' above the top imprint and an unshaded counter at the left.
It also had a single pane of 100 subjects.

Plate 3 had a Type V imprint(Montreal). It had two panes each of 100 subjects.
The left pane had a 'B' above the imprint and a shaded counter at the left.
The right pane had a 'C' above the imprint and a shaded counter at the right.

Plates 1 and Plate 2 were used for the printings at Ottawa in 1872 and at Montreal from 1873 to 1889.
These printings were in various shades of Yellow Brown.

Cover dated January 24 1872 with a pair of Yellow Brown stamps perforated 11.9x11.9

Block of four perforated 11.6x11.9

An example of the first plate perforated 12.0x12.0(Note the shaded counter)

The second plate(first stage, without the "R") perforated 12.0x12.2

The second plate(second stage, "R" for repaired or re-entered added) perforated 12.0x12.0

Stamps from the first two plates can be distinguished by the presence of position dots below the bottom left edge of the stamps in rows two to nine.

The position dot or dots can easily be seen below the lower frame.
In later impressions taken from these plates(IE those in Red brown) the dots tend to grow and in some cases merge due to plate wear.

The second plate continued to be used after printing moved to Ottawa in 1889 but the color changed to Red Brown.

Red Brown perforated 12.0x12.0

Left imprint perforated 12.0x12.0

Right imprint perforated 12.0x12.0

Lower imprint perforated 12.0x12.0

Plate 2 was used to produce imperforate stamps at some point in its life.
These may be favours or printers waste.

Left counter Red Brown

Right imprint Red Brown

These shades don't show up perfectly but they do indicate that there was more than one printing of these imperfs.
