Hey all, I recently acquired a few faucets I finished taking them apart and I did a scratch test to identify the faucets. First few scratches revealed a layer of copper, but further scratching revealed white metal. I hit it with a grinder and no sparks came out, so I am having doubts that it is stainless steel. Please help me identify these faucets.http://i1066.photobucket.com/albums/...ps20mnoo53.jpghttp://i1066.photobucket.com/albums/...pslbmpqlsz.jpg
