Vintage Razor Info

Anybody have any information, or know anything about the below razors? They were given to me by my wife's grandmother, who said that they were her father's.

The first one says "W.R. Case & Sons" on one side of the tang, and "PREMO" on the other.

The second razor says "Anvil Cutlery Works" on the tang and has a "B & H Trademark" etched on the blade. Picture of the trademark did not come out due to the condition of the blade.

Greatly appreciate all your input.

Very difficult to add anything about Case Company. It's great and well known company. You can find a lot info in the internet.
Anvil Cutlery, 1920 - 1921, New Jersey. C.H.Bick - president, J.Hof - secretary.

According "Knives & Razors" by Jim Sargent, such stamp on this Case razor was used until 1915.
