Hi kidvett!
Based on the limited information at hand, it sounds most like a Great War Imperial Contract Red Nine variation. Try comparing it to the pistol pictured here:

If it is identical in characteristics and markings (save serial number) then itâ??s a â??Red Nineâ?. If it isnâ??t identical, note the differences and come back :-)
Warm regards,
Kyrie
