Vintage horse bit.
If you're looking at this you most likely know more about it than me.
If I'm measuring it correctly it's 5", please see photos.
It's stamped as "best solid" on one end and "nickel silver" to the other end.
It also has a stamp across the mouth piece but I can't read most of it but it appears to end JCI&S, don't honestly know if that's the maker or not.
Sorry I can't tell you any more about it.
We have various other pieces of equine equipment to list so please take a scroll through our other items if this may be of interest.
Thanks
Tom.
