When you post items like this,, we need to see the item upright !! Not just the mark !! #1 is the mold number not a mfrs mark at all !! Next is likely a decorators mark !! #3 is a bee hive mark which can be Royal Vienna but can`t tell if this is pottery or porcelain !!
Can`t see anything on the last one !! Please describe what you are posting so we know what we are looking at !!
