I bought this lovely boxwood piccolo off eBay with some money I made from selling on my Basel piccolo to a fella who plays Basel Clique music.
It is ivory, brass, and boxwood. The only markings are a C and the roman Numerals IIV on each piece including each key. It seems to want to play just below a440. I reckon it's on the earlier side of the 1800s rather than the latter based on square keys and general appearance. The embouchure hole is also very small.
It is in excellent condition. I only needed to clean, repad, and make a new headjoint cork.
Here are the photos of getting it playing again:
