私のコックの胴回り、アンチョ・デ・ミ・ペネ

This is how my fingers were when I had my instrument in my hand.

So you can figure how wide it is.

It's like 5 inches, much less wide.

And I was not taking the head, which is like a mushroom, and it's like 2 inches more wide than the whole body of my instrument.

And this is the instrument.
