Shaffer: "7x7, about 16mm. On 1¢ mauve of 1871-1880."

The arrangement seems to reach 17mm at points. The example on Scott No. 76 is a different mark, but fits the root description. See note, below, on round grids of squares.

Usage: Honolulu from September 6, 1854 to October 13, 1855.
One of the "Jupiter" cancels found on the Missionary and Boston Engraved stamps in red or black.
Shaffer: "Bars more even than above [cirgrid20-7(uneven)]. Two or more similar cancels, one with bars farther apart?"

In my own study, the Jupiter cancels found on the Missionary and Boston Engraved stamps are all
cirgrid20-7(uneven), but some strikes are difficult to see well. See note, below, on Jupiter cancels. A later example is noted on Scott No. 33 (lowest illustration on the left), believed to be from the 1870s. This example appears to be from a different device.

Usage: Probably a San Francisco or ship cancel used on loose foreign letters or letters mailed aboard ship in the late 1880's to early 1890's.
Davey: "Circular grid of 8 bars, 20mm., each divided into 9 short slugs, black. 1880's."
Shaffer uses 2-32 for the mark described by Davey as type 12 but says the mark is unconfirmed. I find the example shown matches Davey's description of his type 12.
Shaffer describes 2-33 as "Several similar marks, all probably San Francisco 1880's-early 1890's: 9x9 20mm; 9x11 or 12, 20mm; 8x8 (?) 23mm; 8x10 (?) 22mm."

Types cirgrid20-8 and cirgrid20-9 cover Davey 12 and the 20mm marks included in Shaffer 2-33. Each bar is divided into nine rows of small squares about 20mm diameter arranged 8 x 7, 8 x 9, 9 x 9 or 9 x 12.
Compare types cirgrid22-8 and cirgrid23-8, which are almost indistinguishable. See note, below, on round grids of squares.

Shaffer: "7 bars. 25mm. With sharp dash about 3mm long in center of the middle bar, which usually punches the stamp."

Three of the seven varieties of cirgrid25-7 are quite similar with the rows of bars divided into three parts. I am unsure what mark the blue strikes represent. Finding Shaffer's dash slit is difficult and is impossible to discern from photos.

Davey: "Circular grid of 7 bars, 25mm., black. Fairly common. From Honolulu, 1867-68."
Shaffer: "7 bars without punch pin, 25mm. Honolulu Feb. 10, 1868 – Dec. 20, 1868." Also: "Similar from Waiohinu, Mar. 16, 1881 (size undetermined) – but looks similar."

In this type of cirgrid25-7, the bars are undivided; it is the commonest form of cirgrid25-7. The Waiohinu March 16, 1881 strike is quite similar, if not identical (See Spelman Auction #33, lot 404).

Shaffer 2-21

Usage: Unknown origin; about 1870; noted on Scott No. 31a.
Davey: "Same form as No. 9, with most of each bar cut away, producing a series of regular dashes, thus making a punch cancel or 'scarifying cancel' which penetrated the stamp. Black, 1870."
Shaffer: reserved 2-27 for Davey 3 but had not seen it.

The bars are almost worn away in the lower image shown.
The Lahaina strike seems to match except the dashes do not penetrate and the date is well past the range reported. Could it be a worn strike of cirgrid25-7(undivided bars) or is it a blue strike of one of the cirgrid25-7(3parts) types?

Except for the number of bars and the absence of a reference to a dash slit, the description matches cirgrid25-7(3parts – dash slit). Davey illustrated his type 13 on Plate 1. I wonder whether an 8 bar device exists or whether Davey erred in his description.
