S.E. Shires Q40S

Provenance under review. Reported as China, but the country of manufacture is not yet independently cited — the maker's page does not state one.

Built by Eastman (OEM / parent).

Shires-branded, Eastman-manufactured. Shires' euphonium line is ENTIRELY the Q Series; its Holliston, MA shop builds trumpets/trombones/horns, not these — so a Shires euphonium is not a US-made Shires instrument.
