Set of Spoons from Hamburg with different makers, maker “P.Bm”

[Joerg]

I got this set of spoons from Hamburg, 3 dessert spoons, and 7 coffee spoons. The have the same monogram, are identical in the design but are from different makers. To comply with the forum rules I post each maker separately. Can you help me identify the maker and an approximate manufacturing date? Also, some spoons have a sub-supplier identification number, can you help me with them too?
Thank you, Jörg

Here maker “P.Bm”, the letter of the town mark is “D”, the sub-supplier identification number is 63

I missed some maker marks on the Hamburg page in the World Marks section:

So P.Bm is David Peter Herrmann Baumann, active 1833 until after 1864
