This is a fully engraved Smith & Wesson revolver in American Scroll style featuring a running antelope and antelope tracks. The other side features a grizzly bear head and a grizzly track.
The first two photos show the engraving with the grips off and the other two with the grips on. I always engrave under the grips so no matter what grips are placed, there won’t be any large gaps in the engraving.
