Hello, and thank you for your question.
According to your description, you are referring to a piece in miniature by this famous Germany porcelain maker. Considered the longest continuously operating such maker of the region, and in business - in one form (name) or another since the late 18th century - they have made a wide variety of items including that which you possess. Your piece would be from the early decades of the 20th century and in excellent condition, would have an estimated value of $150-$200 in today's market.
I hope this has been of help to you and has answered your question. (Please remember to click ACCEPT if so.)
Thank you, again.
All the best,
The "32" would have most likely been used a lot or inventory number, not correlating to a date (your piece pre-dates the 1930's.) The P & T refer respectively to the word in German for porcelain, porzellan, and the municipality in which the factory is located, Tettau.
Hoping this has helped further,
Could you please tell me about these three tins? The
