Bob Blackwood is known as a heck of a spur maker. He didn’t make many bits, but the ones he did are highly collectable and rarely available on the used market. This Argentine style curb is marked with Bob’s BB mark, all sweet iron. 5″ mouth, thicker diameter mouth with snaffle joint. This is quite a weighty bit, with a great balance and feel. Short shanks at just 6.75″. Very, very lightly used. Hardly started to rust. Grab this bit while you can, it may be a while until you see another one like it!
