Actually I don't think that anyone has ever heard of it.  I have read
hundreds of books, articles, instruction manuals, guidebooks, etc. about
recording techniques and technology dating from all eras of the
industry, but have never seen anything relating the stamper to the word
"son".  Can you cite me some specific sources in print that use this
term?  I'm not saying that it has never been used, but it must be quite
uncommon, at least in English.
