Could your ten string instrument have been a Puerto Rican Cuatro?

Here's what Lark in the Morning have to say about it...

The instrument is sort of violin-shaped, more rounded like a guitar but with points at the inner bouts like a fiddle. The bridge is a classic guitar type, but the instrument is steel strung and tuned from low to high B E A D G, with the B and E in octaves. It is played with a flatpick and sounds like a cross between a 12-string guitar and a mandolin.

I have one and it has a great sound for it's size.
