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 IDL, the letter of the town mark is probably V

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

So IDL is Johann Diedrich Laué (1808-1824)
Assay master "V" is Johann Heinrich Zell (1816-1826)

So the latest date for the spoon is 1824, wich is about 30 years earlier than I assumed
