Actually removing the bluing is the easy and cheap portion of the job.
There are commercial 'bluing remover' chemicals for that purpose or you can use stuff like 'Naval Jelly' or any of the home brew like vinegar. Most any lightly acidic soln will remove it.
Getting to that point involves complete disassembly if you want to do it correctly. The LCS isn't one of the pop the pins and it falls apart type guns and reassembly seems to make mosts hands tremble though the tried and true Factory methods still work just fine on the bench.
This particular LCS looks heavily machine buffed prior to bluing. Those rounded over corners and washed out engraving lines aren't coming back to life just from removing the bluing.
Some of the metal to metal fit looks pretty severely damaged.
W/o seeing it better, I'd have to wonder if the bbl's haven't gone thru the hot salt blue tank also. That's a real issue to deal with in most instances.
It could use a real restoration not just a bluing removal.
The cut bbls(?),,auction says 'Spl Order Length @ 29"..? but offers no Letter info, the pad, wood cracks and other problems make it a real project gun but on something that may be worth putting some time into at least.
Probably not if you have to pay someone else to do the work though and you're thinking of a profit in a turnover.
