Stag Horn Fork and Steak Knife Set in case. Case is 11" X 9" X 2"
I don't know much about this other than my mother had it in her collection.
This is a vintage mid 20th century, English Sheffield plate boxed set of 12 fork and knife (6 of each) with stag horn handles that were produced by Ashberry.
The company was likely Philip Ashberry and Sons and these were popular wedding and anniversary gift sets from the 1930's through the 1960's. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
