634,935, firearm
643,938 firearm, recoil operated
644,040 firearm ejector mechanism by Bye
643,984 gun magazine bolt by Ross

I find the above firearms related patents for Feb. 20,1900. Have not looked any up, but it seems Bye may have some relationship with Harrington and Richardson.

Later, just checked the Martin Bye patent, and I think that's your gun's patent.
