Those are factory relieved K frame target grips on your Combat Masterpiece, goncalo alves. The checkering pattern would date them to mid 1960's or later. May or may not have the dark washer if you take them off and look inside. In any case, your gun pre-dates the relieved target grips of all kinds. Before that they were using non-relieved target grips.What grips are these on my 1949 era Target Masterpiece? Certain they are not cokes, but can't remember where I got them from. Also have the original numbered to the gun.
