BARONE ASIAN ANTIQUES

I have a really old tea cup and saucer. It's hand painted (rather crudely) for a German tea cup and saucer but it's still exquisite if that makes any sense.

On the bottom it says in red "Made in Germany" in a red circle. It's made out of porcelain.
I always wondered the age of it because this really looks old. However it does say "made in Germany" in English. I was wondering if it was for export.

Here's the weird thing:

I held the bottom of the logo to the light and stamped into the porcelain it says '1811'

Do you think this is a model number (it looks so old to have one!) or do you think it's the date?

thank you
