If I had to guess 50+
5+ spade bits, with different spoons, heights, rollers, braces and cheeks.
About 5 half breeds with different cheeks, acouple with tongue relief
A couple salinas mouthpieces with different cheeks
1 correction with short cheeks
1 square port, short cheeks
10+ snaffles many with different mouthpieces to accommodate colts preferences
(Plus a small pile of of bosals and two rein outfits, but technicaly those are not bits)
Those are ones hanging as outfits. That does not include the tubs I have collected over the years that I don't use that came in trades or bought.
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
