It's London G=1802 and the duty marks is George III. The city mark wasn't used for small items like teaspoons and sugar tongs. The maker's mark is probably upside down and as far as I can see it's TW for Thomas Wallis II.

Crown, anchor and initials look rather prominent for a manufacturer's mark. I've seen that kind of anchor/rope used as a wedding symbol and the initials are for the couple. If you Google anchor and wedding you can see what I mean.

Could be IO for Lawrence Jones and around the first decade of the 18th century. The date letter is rather distorted but it might be M for 1707.

Could be Anders Reinhold Flinkenberg, Simrishamn, Sweden. The hallmarks are pretty worn and I can't see the three crowns mark but the maker's mark looks like AF an the round mark resembles Simrishamn town mark (boat and fish). The date mark appears to have number 3 in it and the letter could be V so...

That's interesting. It appears to be Finnish (part of Sweden at the time) and from Kuopio. The town mark of Kuopio is just the letter C. The year is P2 (or 2P) for 1797 and the maker is Jakob Lindroth (1780-1803). The information is from the book Guld- och silversmeder i Finland 1373-1873 by Tyra Bo...

It's actually Swedish and Stockholm. The town mark is the crowned head of St. Erik, the year letter looks like f=1742 from the time before the three crowns marks was introduced and the maker's marks is that of Henning Peter Henning 1735-59 (1766).

The maker is James Deakin & Sons (John & William F Deakin) and the year 1899.

Johan Gustav Hentzell, Kalmar. The shape of the three crowns mark has varied a lot and I guess it was just standardized in 1901. Anyway D6=1882 is the correct date.

The last word is probably Stettin (Szczecin); also a major Baltic seaport. Tallinn was usually known as Reval until early 20th century.

Harmsen is apparently also a Dutch surname but it doesn't necessarily mean that the spoon is Dutch. I don't think that the letters after Harmsen mean "son" because it would be strange to use normal "s" in Harmsen and then long "s" in "son". And Harmsen is a pa...

Yes, it does look like Kalevala Koru and Helsinki I7=1962. They do have an online archive and based just on the shape of the brooch (rather unusual design for them) it might be solki-1311 (solki=brooch) by Börje Rajalin.

I think it's probably impossible to identify the family without additional information like initials or provenance. Boar's head was a rather common crest and one can't see the color in the engraving so it makes things even more complicated. I'm not sure but the wreath around the boar's head could be...

Unfortunately I have no idea how the volumes are arranged. It seems that each volume just have a selection of noble families starting with princely houses (Fürst) and then counts etc. There doesn't seem to be any geographical division and they don't seem to be arranged according to the date of the c...

Could be James Sutton & James Bult (1782-84) and London. Small items like teaspoons and sugar tongs from London didn't have town mark until later date and the duty mark was introduced in 1784. But teaspoons should have date letters from 1781 onwards. Any change that it has been erased due to pol...

I noticed the direction of the sphinx but I don't think it has any specific meaning here. Usually in heraldry the charges are facing right (from the point of view of the holder of the shield). If they are facing left it should be specified in the blazon. On the other hand the charges of coat of arms...

This could be the one for von Morsky (Grafen von Morsky) although there might be other families who have a as a charge. If the hatching is made according to the standard practice the shield should be red like in the Morsky coat of arms. If you have time you might be able to find some of the other co...

That appears to be the coat of arms of Count Anton von Prokesch-Osten.

Might be William Cecil, Baron Burghley, adviser of Queen Elizabeth I. At least the beard style and hat look similar. I don't know how much likeness one can expect with this kind of portrait. But of course one can't be 100% sure and he could be almost any 16th century elderly bearded gentleman. https...

Here's a link to the index part: https://archive.org/details/fairbairnsbookof01fair/page/106/mode/2up Following families used the crest: Atkin, Atkins, Atkyns, Bratt, Lysons. None of those matches the initials but they might be later. But it's rather difficult to determine if the ladle belonged to s...

It's a crest so a heraldic symbol indicating the family that owned the ladle. Looks like they creatures could be greyhounds and a similar crest can be found here (bottom left corner): https://archive.org/details/fairbairnsbookof02fair/page/n123/mode/2up You should find the index part of Fairbairn's ...
