Set of Knives and Forks

Not sure what the marks are on these knives…any help identifying whether they are sterling or plate?

I have not seen these exact markings before so cannot say who the manufacturer is, but they are very typical of electroplate marks. They are certainly not silver/sterling marks.

I suspected it was electroplate… especially since the forks do not have any marks on them…sterling would have marks on every piece…thanks so much for your help
