Hi yaterbob.....welcome to TFF.
Well, there's good news & bad news.
The good news: It's a beautiful rifle, obviously professionally very well done.
The bad news: Once you modify or change a military rifle, it's collector value is gone....and, unless it's modified and marked
by a recognized custom gunsmith, it's value decreases considerably.
Back after WWI & WWII, old surplus '03s and 03A3s were a dime a dozen and thousands were converted to "sporters" & "hunters". Who knew that these old warhorses, in original GI condition, would become "collector's items" and far outvalue those converted to sporters.....even beautifully done ones like yours.
As to value.....the only real answer is "whatever somebody will pay". My guess would be in the $400-$600 range.
