Just use it for paper weight,the time spent on this pitted gun is really foolish. Crazy Horse I think you may want to start with surface grinder.J.J.

Leave it alone,take it to the road show.
Might be Nimschki first gun,or Kornbrath ,or who knows.??????
That surface is so rough,i would bet it could be completely overlaid with fine gold sheet,with out cross hatching the surface.

I know it would take some time, so only worth if this is a valuable piece. The engraving doesn’t look like a nice engraving, looks more like a “stamp”. But the cuts can’t be that deep, sure deeper than the scratches itself.
Being a goldsmith I know what it is to remove scratches, can’t be that hard unless if you remove say 0.3 mm from the surface, the whole thing becomes too small.
From the looksof those pits it would take a very long time to draw file it down by hand. J.J. is correct; one would need to place it on a surface grinder to eliminate all of those pits.
Tollerance is the virtue of a man without convictions.
If the '73 is in the same shape, I would probably pass, as the side plates will be thin when you get done. Probably too thin. The '92 is more salvagable, but will take a lot of work, and you will have to charge what will seem like too much to be able to make your time worthwhile. This is a project that would be termed a "labor of love". In other words, the engraver or the owner has to have a deep emotional attachment to the piece to make it viable. The project probably has no commercial upside. Sorry.
Thanks all for the feed back
Because this project is a collaborative effort with the gunsmith and will use this as a learning lesson, the labor is not a concern, (this is not my day job) the time invested will be well spent. Learning the processes is my goal. I get request to do and help on various project and have turn them away in the past, but this project with the age of these guns I felt would be a challenge and fun.
I may add the 1873 is by far in better condition I have the side plates already complete and almost completed with 1 side of the receiver. The 1892 looked from the start to be more challenging piece.
When it’s complete I will post he before and after pictures
It's great that you can go forward with this project. Being able to afford to do it is a precious thing as an old shooter like this would most likely end up parted out or maybe even worse. A similar conversation, with a customer, indirectly through my gunsmith yielded the same financial sentiments previously stated ... basically, if it isn't documented to be the rifle used to shoot Lucky Ned Pepper in the meadow then it is better to let it go.
Here's a way to proceed to preserve as much of the original material as possible ....
Take a smoke pull of the engraving and possibly a casting to get the correct depth of the engraving. Not crucially important in this case but a casting will also reveal the hammer stroke marks left by the chisel if there are any visible.
Use finishing files to take the metal down evenly. Go down as far as you can to remove the light pitting. At this point there will be only a few really deep pits left and maybe 10 to 20 percent of the engraving remaining.
For the remaining deep pits, you can use either a jeweler's laser welder as mentioned previously or a TIG welder. For the laser welder, shave pieces of steel off the underside/inside of the upper/lower tang so the replacement metal to fill the pits is exactly the same. Use these pieces to melt into the pits with the jeweler's laser. If you use a TIG, use mild steel rod. Nickel steel rod if the gun of a later manufacture. Matching the steel helps in the ease of final finishing. If you don't have access to that equipment, burnish in the pits as the steel on these old guns is soft enough to move pretty far ... as much as 1/16" of an inch easily. If do you use a welder, case color or charcoal blue.
Use files again to bring everything flush then oil stones and bring to a 400 grit finish.
You can then transfer your pattern back on to the action and replicate it exactly after the wood has been refitted.
Someday they these oldies will be gone and every one saved from the rust and rot brings a piece of great American history back into circulation ... hopefully for another century of enjoyment. Best of luck .... Chris

Thanks Chris you actually answered what I needed to know. I was going down the path you laid out for the most part but I was not sure it was the best way.
The welding part I really never explored. Would a spot or tack weld work as well or is this not wise? Thanks again
That kind of welding is not going to help as you need to literally add metal rather than attach it. A tack weld will most likely break anyway if you had to burnish that area and there's a good chance you will need to as it is difficult to fill a hole perfectly. If you do find the need to weld, I'd suggest case coloring or charcoal blue as a final finish as hot bluing is something I've never attempted. The Winchesters I've done welding on will be case colored.
The year of your 92 will play a role in what you can do for finishing ... Winchester ceased offering casing on those in 1901 or 1904 (one of those years is correct if I recall).
Try to burnish in as much as you can as you file this down. Don't be concerned with saving the original engraving and focus more on using the higher metal to your advantage in filling the low spots. The burnisher I use is one from GRS with a slight modification to the edges (polished over). In the pneumatic handpieces it moves a lot of metal across the surface of these old guns. You may find that many of the pits become deep pinholes as you near the end of your filing work and I was able to save a lot of metal on my 73 simply by burnishing. That will be your best bet if you intend to hot blue. Just be sure all of the rust is out. It worked great on an old barrel and the surface was good after hot bluing with no evidence that it was burnished prior to stoning and sanding.
You'll just have to get in there and work it. Treat welding as a very very last resort and not a shortcut and you'll find that you may not need to do it at all. Everything that is learned along the way on this one will help you keep more of your shirt (rather than losing all of it ) when a project of greater value comes along.
Have fun ...
