Bair either merged or was purchased by Pacific which later was purchased by Hornady. You are correct Hornady bushings do fit the Bair machine. Since these machines have not been made in decades finding parts may be difficult. I see some old machines & parts from time to time on e-bay, or perhaps you'll get lucky here and some one will have some. You should also look to see Hornady parts may interchange or might be adapted. Bair made good solid equipment, I know of several that are still in use. Good luck.
