What does this "teapot" mark mean?

[BP1051]

Hi,

I have a small silver plate showing in below pics. There is a silversmith mark representing Jozsef Ullamnn and a Diana head, I can recognized them. But there is another small mark like a teapot (?) inside. Anyone familiar with this? Thanks in advance!

Hi,
P is letter code for Budapest. Ullmann could be a retailer (guessing) because I have seen Thonet furniture with his name.
I am sure teapot silversmith`s mark will be recognized.
