During the "Patent era" (1875-1915) Peterson's pipes hadn't any Country of Manufacture stamped. Despite worn hallmarks (see enlarged view) this pipe nevertheless may be dated. The shield shape of the three escutcheons indicates a pre-1896 pipe. The year letter can only be a "Z" making this pipe to reach back to 1895.
The shank/stem gap: one of Peterson's odd particularity. The tenon is slightly tapered so even if the briar or the stem material shrinks or expands the stem can still be inserted tightly. This allows to safely remove and replace stem while pipe is hot.
The enlarged views display the tenon extension (the condensor). In the early years, Peterson used horn condensors (this pipe) for their Deluxe and Premier series. Sometime in the 1940's they changed to bakelite and finally to aluminum nowadays.

The silver hallmarks correspond to 1899 (see document).
The "2" after the word "Patent" indicates the second-highest grade offered. This pipe from the Patent era shows no fills.

▲ No stem markings.
No mention of "Ireland" nor "Eire" nor "Irish Free State" on the shank.

▲ Pre-republic era (Before 1949).
Notice the Country of Manufacture stamp in two lines and block letters.

The first two escutcheon in Peterson's genuine silver hallmark are a Hibernia and a Harp. The first mark on the band of this pipe is a Shamrock denoting a non silver metal, probably nickel. These faux hallmarks cannot be of any help to date the pipe.
The "Irish Free State" mark was adopted in 1922 and replaced by "Eire" in 1937.
- The Irish Free State was formed on 15 January 1922.
- Eire was formed on 29 December 1937.
This unsmoked pipe should have been crafted in this period of time.

▲ The "Made in Eire" stamped in circle means that this pipe dates from 1938 to 1947.

Peterson's Millenium pipe commemorates the City of Dublin's founding (988-1988).

▲ This pipe is part of the 2nd numbered edition (1000 pipes) of a serie celabrating the writer's 150th birthday anniversary.

▲ Peterson started producing Mark Twains without numbers from 1983 through 89. This piece is one of these. The band is 1981 [p] hallmarked. This seems to be a contradiction but an explaination may be found here.

The stem of this meerschaum pipe is horn and it constitutes a rare example of a P-Lip carved into this material.
The band on the pipe is sterling silver not validated by hallmarks making thus this pipe impossible to date.

The Antique collection is supposed to commemorate Peterson's historical shapes. The markings on the four pipes replicas making up the collection simulate the Pre-Republic era stampings (forked tail P and "Made in Ireland"). The only authentic marks on these pipes are the hallmarks on the band with a year letter [K] in this case, standing for 1996.
"1903" on the band indicates the year this Dublin shape first appeared in Peterson's offer. (Name of the model: Dublin c. 1903)
