First off welcome to the Forum; we're glad to have you join. Would love to see additional pictures showing all the engraved work. As you inherited it, see if you can discover anything in estate records showing who did the work as that may help in establishing value. As colt_ssa indicated in post #4 and from what I can see, the work looks very well executed; and while the revolver itself could accurately be characterized as a "budget conscious" firearm, it obviously held enough value to it's owner - for whatever reason - to justify their making a significant investment having this work done. Hope you'll stick around and share more information with you, and once again welcome!
