In this case the bands are brass, perhaps with more tin and less copper.  I tested the bands in the process.  No silver content in them what-so-ever, not even an over lay.  Yes, some brass shines up very near white metal when the copper content is lower.  I would place these as inbetween white metal and yellow brass.  The more copper content, the redder and/or yellower it becomes.  Sometimes it is hard to tell the difference at first glance between newely shined whiter brass, silver, and white metal.
