Thanks for the response and info.
This set and a few other pieces were actually some of the first silver I bought when I was in high school in 1971 from a classified ad. I have no other information about the set and there are no markings on the presentation case. It could have been a custom set?
This fork set is one of the other pieces I bought at that time from the same person, it has no markings but I think the handles tested as silver/coin silver. I'm just starting to dig out all the silver I have so I can ID it all.
