RS Prussia Mold 502?

Picked up this creamer. Looks exactly like a mustard pot I have. Is this Mold 502?

 

Can you hear me coveting!! Love that stuff; it's the china version of Fragonard and Boucher. About 15 years ago, I bought a sugar and creamer at a tag sale. I VOWED I would only buy future pieces that appeared serendipitously (and inexpensively) on my horizon.

I have only about eight pieces, but it is enough to enable me to equip a tea table with toast, tea, and strawberries and cream, and with me in my satin robe...and a good book...and a bit of Praetorius playing...

OK -- so I'm just a tad fanciful.

 

Hi,
So for some reason forum still doesn't let me start my own threads so I am going to resurrect this one.
Someone maybe has more info on these pieces that I picked up on auction. There is a prevalent amount of info on Internet on how apparently those are made in post WWII Poland in 50s However I think this can be easily debunked by anyone who has the slightest idea about political situation in eastern block in 50s. Production of something that says Made in German Poland would simply not fly with Bierut being the First Secretary.
I am opting more towards late partition Era about 2 decades or so before Poland regained it's independence, the famed Tillowitz factory was at that time located in Prussia which was at the time former territory of 1st polish Republic hence I think Made in (German) Poland on mark would make complete sense for the time period before 1918.
Also there is one or 2 pieces that have mark different than Poland China. Anyone has more info, or maybe has the same set?
