I didn't think they were an option until the mid 50's but the super C I grew up with had a 2 point fast hitch so maybe they were an option with the letter series. My 1955 100 was missing it but I lucked out and found one around 10 years ago for $100, of course it is still on a pallet in the barn. I found this one on CL and that is about what I see them listed for around here.
