Grammar correct or not, the etch style is highly dubious. The text below is a Letraset font developed in the 60's and used still today. There are variations of this font style and you will see this exact font on many a fake dedication.

If you see an inscription with this script style, it has big problems. This style of letting would not have been used by period scribes who executed dedications by pen & hand.
