I too have a heavily engraved Trojan. A gunsmith said it was probably an apprentice engraver's exam submittal for him to be certified. It has silver inlays as well as the engraving. The stock is plain except for checkering and, because of the lack of excessive drop and the finer LPI checkering, I think it is a replacement. I have tried to attach photos
