Lightly engraved Mauser action and trigger guard floorplate assembly. This is in a semi-English style of engraving. This is a classic style that looks very good on bolt action rifles without full-coverage.

Gouse Freelance Firearms Engraving
Superior Quality Workmanship from Renowned Master Gun Engraver, Michael Gouse
When I engrave 50% coverage revolvers, I always engrave under the grip area so, if at a later date, you wish to put on a different grip, you don’t have an unsightly gap in the engraving.
