,Send me a picture or tracing of the right hand hammer, and include all pertinent dims. I may have a LH hammer in my "cigar boxed inventory" that might work-- I have two trigger guard bows at present, both from field grade L.C. Smiths- pre-1913 with the two set screw holes-- if that might give you something to work with. I have never worked on a Crescent shotgun, so this is just a "shot in the dark" but if I can assist with this restoration project, OK--RWTF
