Nice pictures..
At a minimum,,and this is just my opinion just like anyone elses,,,
>
Refinished case colors on frame, forend, toplever.
Refinished trigger guard blue
TG engraving looks lightly polished over to brighten polish up,,even then the 'blue' isn't right for the gun. Of course it could just be the picture.
Refinished wood w/ recut checkering
Wrong FE for the gun I think (re#'d if it is)
BBl set from another gun,, that had a flat rib to begin with. (Maybe the original was blown, pitted,,whatever)
Top rib marks were not of the correct type for the 4, so they were filed off/removed. New markings and top rib border engraving added. The area in front of the gold bar is obviously (to me) been hand stamped enhanced in an attempt to mimic the original LCS fine dot pattern.
I'd guess it could have been damaged when a not so careful workperson removed the original marks.
But looking at the photo of it
http://i275.photobucket.com/albums/jj304/romac2/LC%20Smith/039.jpg notice the shadow along the top edge of the top rib it casts onto the right tube.
The shadow shows that the top rib was purposely filed down at a slope beginning at the hand matted area then down slightly to hit the receiver breech.
The only thing the 'craftsperson' could do then was an attempt to touch up the matting ahead of the gold bar by hand.
The bbl lug (that shows through the frame on the bottom) doesn't fit the frame very well in the pic I see of it. The lug itself is rounded over on it's edges, then engraved. It just has that look of coming from a worn and used set of bbls, having been polished and squared up as best can be, cut and blued.
**added: I had originaly thought perhaps a half sole job had been done on a replacement bbl to add the needed look of the longer rear rib portion.
Something that's done to use a lowe grade bbl on a high(er grade LCS where the longer rear rib portion is needed.
I can't see that it's been done in any of the new pics. If they did, it hid well,, and they put in a false splice line under the new gold bar placement. The remains of the old one usually can be seen yet but takes a close look. **
The bbl 4E marks looks punched in over a weld or in the least different from the rest and not a clean mark. Something was filled in beneath it.
The NP proof marks look faint and double struck from rebound effect. Redone proof marks, poorly done or polished over originals, ,,,,tough to tell from that'd pic but they draw my attention. Maybe just the flash in the picture..
With out the gun in hand but with the major things I see wrong and just a guess from the pics,,I'd also suspect it may be a full upgrade to a 4E including changing of ser# and grade markings.
The serial number stamps themselves just look too new in style to me.
Closer examination of the marks and gun in general are needed for that of course.
That would be an interesting one to look inside of!
Alot about the gun is very new,
along with some old looking areas of the inlet edges of the wood,,and those twisted screw driver slots. I guess those show up everywhere!
Again,,just my observations..
