Limoges tea set?

Another find from today. Consists of 10 trios, a sugar bowl, creamer and two serving plates. It is very thin porcelain, almost on par with egg shell. There is not much by way of marks to identify it other than the numerals '2145'. There are also some impressed numbers but these just seem to be part numbers for the set I would say. It looks like something that has come out of Limoges looking at the gold highlights and shape of the pieces. Other than that I am clueless and Google isn't being my friend. Any other ideas, please?

 

Written numbers like that would be very atypical of Limoges. My suspicion is German or Austrian. The Austrians especially did a lot of porcelain that closely resembles Limoges. If the same number is written on all the pieces it would most likely be the pattern number. If the impressed numbers differ depending on shape than it's the shape number.

 

Okay thanks for the heads up. The written numbers are only on the creamer and one other piece. The impressed numbers are also scarce. It's all a bit odd.
