Back in the day, well, meaning 2002-2004....GC had ships of these things on a big buy from Russia. Their cost was $25/each for the body and card cap.....
They used them as loss leaders for a few years....sometimes reducing their internal cost to a penny (.01) to make a $25 sale worth while on their books.
Not sure if these were indeed Chinese "fakes" or not but they were cheap and I grabbed up a few on different occasions, kept a couple for myself and have given away or traded the others away.
EDIT: I'm almost certain these were indeed the Russian's...as there were hand drawn mic specs on "newspaper" type paper when I bought them. Russian writing on all documentation, as well.
