Older horse BIT - stamped BB ported w/ 4 moving rings copper inlays & sweet iron

Description

sweet iron shanked bit - maker stamped BB and mouth has a port with 4 rings.  Mouth also has copper inlays.  It's an older bit that was in use in Wickenburg, Arizona on rope horses.  I am not positive of maker - as I cannot locate any exactly like it - but BB was the stamp used by Bob Blackwood and the markings on this do look like the ones on his spurs.
