This Triumph Soprano Cornet was spotted on eBay in the 2000's. Serial number is 12xxx.
The history as provided by the seller was that his Grandfather acquired the soprano cornet from new. It came with a number of original era mouthpieces, lyre, early printed music and the original case.
It was in very reasonable condition for the age, and appeared to be untouched. It has had a mild restoration to remove a few blemishes and restore valve compression.
Records indicate this instrument was manufactured before June 1911, estimated before 31 December 1908.
