It's a little cob, looks like 1/2 reale weight. I have the similar cross pattern on one if you look in my last colonial post. There's a few varieties. But Daniel Sedwick, writes books on them, said mine was most likely Bogota Columbia. If you send him photos of yours he can give you the best info. His book is great too.
Also, congrats on it!!! I got my first two and can't stop staring at them!
