MINIATURE GOUDA VASE REGINA

I BOUGHT THIS TINY VASE FOR £5.00 RECOGNIZING IT TO BE GOUDA POTTERY. IT STANDS APPROX 21/4" HIGH IN PERFECT CONDITION. RESEARCH TELLS ME IT IS A MATT REGINA PATTERN.
WHAT I WOULD LIKE TO KNOW IS HOW OLD IT IS AND WHAT THE NUMBERS ON THE BASE SIGNIFY BUT EVEN MORE INTERESTING IS WHY DOES IT HAVE ECHTERNACH ON IT . ECHTERNACH IS THE OLDEST TOWN IN LUXEMBOURG NEAR THE BORDER OF GERMANY.

ANY INFO WOULD BE APPRECIATED.
