Adjust Fit of My New Saddle and Bridles

I had an old WW I calvary saddle, It was the best and the fit was perfect.The Bridle was the issue we went to halter style no bit.Misty had a very delicate mouth and responded to clicks and taps. One day I can home and the saddle was sold. about a month later I came home and the horse was sold, this was a tight economic time for my parents so My horse was the last of 7 to be sold. Many ears later I met the Man the purchased my saddle. He never used it. He has it on display in his house. It was fun to see it again.
