If it's still in round... it's worth it! I would take that to the nearest plater, have them strip the shell and lugs and I'd pay whatever they ask if they can revive the black brass and re-plate the lugs, butt plate and strainer in gold.It would be worth it. That's a floral pattern 5x14, you can't touch those for under 2/3 grand. A 'refurb' (if done right) and that drum will still have serious value.Pain in the a$$ to restore, but well worth the effort.John
It doesn`t look like the gunmetal or Brass is damaged. Trichloroethylene or a commercial solvent similar should remove most junk by soaking it in it.
