You can still return both items under a false ad listing because both items were not pewter and listed as so. If you buy something off eBay it’s damaged or a misrepresented listing eBay has a buyer money back guarantee buyer protection policy whether it’s listed as no returns or not. File a return with eBay and it will get refunded. Just put in the comments item was falsely listed as pewter and it’s not.
The Salvation Army, good will, and local thrift stores have pewter here every week. Some to way to high priced and some cheap. Look under the pewter picture posts on the forum and start shopping locally.
