Paul Muller Bavaria China - Warranted 18 Carat Gold

I inherited this china from my mom.  These plates are stamped on the backside with "warranted" 18 carat Gold, Paul Muller Selb Bavaria.  However, some of the china with the same exact pattern is stamped with Hutschenreuther with a Gold Lion. I'd appreciated any input from anyone who knows anything about this china.  I've searched the net on some history.  And I did find this pattern from www.replacements.com but didn't find much info such as history and current cost.  Attached are photos from www.replacements.com of the pattern.  Thanks in advance.
