Runs, the joint check that was on all Syracuse hammer and hammerless guns carried over to the Fulton era Hunter Arms guns until 1899 when the joint check was eliminated. However Hunter Arms did make another joint check and I did not research how long it was made but a Specialty Grade I own from 1913 has one. I had read that if the spring breaks you will have a tough time removing the barrel from the receiver.
