Hello and welcome to this great and very informative place. I joined this community not long ago, and learned quite a lot in the last months about gen and rep. To answer your question, I copy the answer to the question I asked a couple of weeks ago:
"MBW= Mariah Best Watches (the name that is given to an specific manufacturer who in the past sold the watches by Mariah
MBK= a Big mall place, soping mall where the shop of MBW is allocated. "
I really suggest to use the advanced search option-it's a lot of reading, but also brings you new ideas and access to a couple of watches and members!
Enjoy, J
