PICTURES ADDED: ID needed please: Silver fork, plate and sugar spoon...

[Chuck the AGgie]

I have three items I need help identifying- can't find any info anywhere on them. First is a "silver" looking fork that reads (on back) "16" space "A.H. SMITH". If you look at it upside down (from the name) it could be a "9" or "19". Second and third have the same mark. A "silver" plate with no markings anywhere except on the engraved topside, which has a "o" mark. The sugar spoon has the same "o" mark on the underside of the spoon part.

Any help identifying these items would be appreciated. Who made them and if they're real silver or just silver plated?

Thanks,
