Leon Powers rebuild

My girlfriend's grandfather was one of the best cowboys in this or any other part of the country. Her uncle found this old saddle of his and gave it to her brother. I was honored when he asked me to rebuild it for him. I think it is an old association tree and I stripped it down leaving only the gullet. I have the front jockey, back jockey, seat and fenders that came off the saddle that will be reused when it's ready. Ant tips on matching the color of the old leather with the new would be greatly appreciated.
