Silver egg cup stand - help with country of origin and date

[lividel]

Hi, I have a 5 cup eggcup stand with 5 spoons. I cannot get a clear photo of the hallmark but it has 4 images.
First looks like J S & S within a shield, second is an animal with a long snout (like an anteater), third is a small crown and fourth is the letter B.
I am curious to find out where it was made and when it was made.
As you can see from the photo, the flat base is attached to the spoon rack by a wing nut. The pattern on the base also shows slightly on the underside of the base. Any help would be appreciated. Thanks.

Looks like it is British in style but need to see the mark if possible. If you cannot get photo up here, please E-mail one to me. Best wishes, Mike.

Hi, thanks for taking the time to have a look for me.
I just can't get the hallmark in focus. The best i could do is sketch it. See pic attached.

Thanks anyway Mike.

Your ant-eater is in fact a beaver! The maker is J Sherwood & Sons of Birmingham, England.

Thanks Neruda, have you any idea of the date?

My feeling, based on style is 1870s or 1880s. The crown mark on English silverplate copied the assay office mark for Sheffield sterling silver, thus creating a conveniently ambiguous situation. This confusing practice was prohibited around the mid 1880s.
Some silverplate manufacturers did use date codes - again loosely copying the system for sterling. I don't know if this was the case with Sherwood - but possibly the letter "B" is a date reference?
