OK, I'm not familiar with the Brownie TGP but I'll try to be a good GFY citizen and offer up these links as possible sources of information.

Maybe even use Archive.org's pages to see if they might have archived Germesia's forum somewhere in one of their visits.

(you may have to search a number of years...)
My apologies in advance if I've just shown myself to be a clueless idiot.
Good luck, I hope you find a solution to your problem(s).
