Can you measure your horse from one corner of his mouth, across his poll and down to the other corner of his mouth? I definitely have the noseband and the reins.
Well, my bridle right now is 39" from one end of the bit to the other. Any luck?
Also, I looked Saddle Seat up on Wikipedia because I knew nothing about it. It sounds like an interesting sport; I'm envious of the brightly colored girths! XD Wiki said that double bridles are usually used, though, is that the kind that you have? I only ask because I'm looking for a snaffle bridle.
