I HAVE JUST ACQUIRED AN ESTATE THAT HAS A BROWN ON BOWN SUGAR BOWL. I THINK IT IS A PERUVIAN HORSE HUNT PATTERN. THERE IS ABSOLUTELY NO WHITE OR CREAM COLOR ON THIS BOWL. IT IS ALL BROWN. SOLID BROWN ON THE INSIDE OF THE BOWL AND BROWN ON BROWN ON THE OUTSIDE. I HAVE NOT SEEN APIECE LIKE THIS BEFORE. IS THIS A RARE PIECE? THERE IS A DIAMOND MARKER ON THE BOTTOM OF THE BOWL.
THE MIDDLE OF THE DIAMOND HAS A CAPITOL R AND SMALL A. LEFT SIDE HAS AN R AND RIGHT SIDE HAS AN 8. TOP OF DIAMOND HAS AN A AND BELOW AN AL, AND OPPOSITE SIDE HAS AN L. THE ONLY OTHER MARKING IS AN M STAMPED INTO THE BOTTOM OF THE BOWL. THANKS FOR YOUR HELP.
