I'm probably gonna kick myself if it's something obvious, but I can't tell from the photos.

Looks interesting enough.

 

[Kritavi]

Appears to be a Nach Meyer flute from the 19th century.

 

[kymarto]

It's a simple system flute keyed to C, probably from around 1880 or so. One key very definitely appears broken.
