The maker looks like Deakin and Francis.
.

The mark looks like a "b" for 1894 to me and I believe the maker is Allen and Darwin

Have a look at Birmingham 1932 mark. Its a souvenier spoon

As an alternative - to me the 2nd mark illusion is the Brittania mark.
Is there any chance that the third mark could be a Harp Crowned rather than "gt", which then make Hibernia the logical mark.

Really need a picture. If the bar mark is H B & S then I believe Herbert Bushell & Son would be a better match

The mark is for London 1744, and the maker is William Cripps.

The top mark is the British Registry Design mark. You can check this at British registry date numbers this site. http://www.925-1000.com/registry.html" onclick="window.open(this.href);return false; This is not the manufacture date, but would not be earlier. The mark is table 2 but the year date lett...

Isaac
Are you sure it is not RT&Co with the o lined up with the top of the C
There is an unattributed mark for this with similar punch outline and period.

A wild guess - a points recorder such as a crib board or for card games

Assuming the around 1770 date, I think that the IL mark is going to be difficult to put to a specific maker. The I central dot L could be one of John Laughlan, Senior., John Lloyd, Senior., or John Locker. may be others. There is an IL in a shaped mark attributed to a John Laughlan but does not have...

For interest: Roberts and Belk Lamp mark was also used on some sterling silver also there was a London sterling mark entered in 1906 which was still in use in 1957. This mark has a completely different "&" to that in use in the other assay offices including a rounded top and the lower ...

Have a look under British hallmarks on this site under Birmingham. Is it the 1857, 1858 set of marks.
The head, if it is the sovereigns head, would be the duty mark if it is British sterling silver

Kerangoumar. I think you are getting away from the point. In 1820 the Government Impost or Duty was based on weight of finished item. Using the method used above which is basically dividing duty in pence per troy oz. by what is basically a bullion price for silver per troy oz. and saying it is 90%, ...

I am a bit confused by all this mathematics (old age galloping on?). I am trying to understand how dividing the duty (on 1 ounce of the silver articles assayed weight) in coinage of the realm (18 pennies or "d") by its troy weight of 20 pennyweight (dwt) which is 1 ounce, and saying it is ...

Hose - When a maker has SUPER A1 or Super A1 plus say 10 penny weight (DWTS)., where does that leave A1 if A1 is best quality of the maker

The mark you are showing (poor image on my screen) appears to be a British Registry Mark). If you go to this site Home page ,under Other Onsite Resources is British Registry Dates - hopefully you can confirm this under table 2, which will give the year the design was registered

Really need a photo of these marks, but taking a guess go to the British Marks on this site, then Sheffield makers and have a look at Harrison Brothers mark. If this is same as your H B, I would suggest it could be Sheffield 1979 unless you know they are older. Some body with more computer skills ma...

The 1924 I is a straight vertical line with a curve off to the left at the top.
The 1926 L is is not quite vertical with a hook shape curve to the right on the bottom
My computer skills are not up to copy marks from the book to the site but I am sure somebody will do this to make it clearer.

What is the left hand mark that looks like a head? All marks are not really clear on the screen but the year mark looks more like the 1924 letter You say the makers mark is FTS & son, is that the bottom mark that looks like West and Son to me, who would be the maker although they also may use an...

Is the maker Henry Williams or as I have Henry Williamson Ltd recorded for this mark?
