The 29-year-old musician says he was on an N train in Queens last week and nodded off. When he awoke as he approached the last stop, he noticed his black leather case was missing.
Police say the case held the curvy, Swiss-made horn and a Bach Stradivarius trumpet. The flugelhorn retails for more than $5,000, the trumpet for about $2,000.
The musician reported the theft Monday.
Police are asking for anyone with information to call them.
