...and if you try vinegar use white - not red wine. Some of that corrosion can only be removed with physical scraping but do NOT do that! We can see the manufacturer logo well enough. Regarding value, please understand this forum is not an appraisal service. A member may PM you with more info but we encourage all to look at similar items on the web through auction sales sites or dealers to find the value. Neil
