Instrument

A quick Google says it's a common wooden flute made by Emil Rittershausen in Germany, formerly sold by Carl Fischer Music in the US. Obviously an old instrument, could t find a model number or anything.

its a clarinet

Pretty sure it's a bass flute of some kind.

Ayy, lovely! If I were you I'd play it a few times and then show off my skills to people who'd have no idea what the instrument is

Bass flute would be larger, wouldn't it? At least the western ones are massive

Thanks bro you're a real nibba
