What you're saying sounds iffy. Here is a decent article on the gray/grey market: http://www.extraordinaryinvestor.com/grey-sheets.html . It says:
"No recent bid or ask quotes are available because no market makers share data or quote such stocks. There is no quoting system available to record and settle trades.

All Grey sheet trading is moderated by a broker and done between consenting individuals at a price they agree on. The only documentation that can be publicly found regarding the trades is when the last trade took place."

So there are no market makers per se. The question is what is the meaning of "moderated by a broker."
