Dove-I finally found the bit Western Bits
it is the second one down it is extremely similar except mine might have a little copper. This is the same bit the previous owners used as well...
I will see what I can do about his teeth he is eating fine so I will look.
About his back...I was massaging him the other day and he didn't try to pull away. Could it be since he was sitting and barely had a saddle on he's still getting used to it, and will later calm down????
Thanks for everyones help soo far! ;)
