This is one of the sets @Jrdelgado sent me after removing the black oxidation from the case. I used the vinegar, salt and baking soda method and it worked out great. Then a little polishing to get the shine back. I didn't have white vinegar, but apple cider vinegar worked fine. I looked at Achim's site, @mr-razor, but couldn't find this one. The case has a smooth silver finish and you can see that the handle is different. The body of the handle is noticeably thinner and there is no knurling on the bottom ball of the handle. Also, the bottom is flat compared to other old type handles that are rounded.
