Hello Jay,
Sorry, no; I do not know who or where the engraving was done.
This luger's engraving and carved grips do look alot like some of the samples in R. Gibson's "The Krieghoff Parabellum" on pages 199 thru 213...
Maybe our Forum's leader, John Dunkle, might add his comments... <img src="graemlins/yltype.gif" border="0" alt="[typing]" />
