Going to be blunt...
If the forearm numbers match the buttstock/buttplate numbers, you did just peachy for a very nice factory drilled and tapped 99EG. They aren't that common. Though from the shine I think somebody added a coat or three of tung oil or some such.
And whether it's correct or not, I'll bet when you're tired of it in 5 or 10 years that you won't have too much trouble selling it for $600 or more at a local gun show.
Very classy hunting rifle right there.
