IDEA (Italy) Smooth Straight Billiard, Army Mount, 9mm — Modern Era, Undetermined Date

The billiard is the foundational shape of the classical pipe canon: a cylindrical bowl of roughly even wall thickness, set at a right angle to a shank of comparable length, with a straight stem completing the line. Its proportions have served for over a century as the benchmark against which other shapes are measured, and nearly every factory catalogue in Europe has anchored its range with a billiard. The army mount — also called a military mount — is a construction in which the stem's tenon inserts directly into the reinforced end of the shank rather than into a drilled mortise of conventional depth. The design traces its popular name to trench-era practicality: the stem could be removed or seated even while the pipe was warm, and the mount protected the shank face against splitting. The 9mm filter bore is the standard of the German-speaking and broader continental market, accommodating disposable charcoal filters and indicating a pipe engineered for that smoking tradition.

Italy has been one of the world's principal pipemaking nations since the mid-twentieth century, its workshops ranging from large factory operations to small artisan benches. IDEA belongs to this Italian production landscape, and the brand attribution here rests on the owner's statement. The pipe carries no factory date-coding system of the kind used by houses such as Dunhill, so its dating must remain a broad bracket: a modern-era Italian pipe, its precise year of manufacture undetermined.
