The bridle is warmblood size. I used it on my 16.3hh Hanoverian. I am asking $150. It was only used for one season for the same horse I used the girth on.
I also have the bits for that bridle. The Sprenger german silver curb for $125 (new they are $260 and up) and the Sprenger german silver bridoon for $30 (new they are $60).
Let me know if you have any more questions.
