I recently acquired what appears to be a very original Model 1887 12G shotgun with serial # 45729.  Turns out the left side frame screw that provides the pivot point for the carrier is stripped and needs to be replaced.  Thankfully the threads in the receiver are ok.  I have not been able to locate a good parts schematic for the original model 1887 to pull a part description.  

–  Can any WACA members out there provide me with a part description or better yet, a schematic for this model?

–  Any ideas on a supplier for this part?  Preferably a used screw that would better match the patina of this great old gun. 

Thanks in advance,

Jim
