American 18S PW Case Mark ID

[fijidad]

I've been unable to find this mark on the web or in the information I have at hand...can anyone tell me if this mark indicates GF or solid gold?

Warranted always = Gold Filled.

 

[Rick Hufnagel]

Gold filled as roughbarked said, and made by H Muhr of Philadelphia.

 

[Jim Haney]

As per Roy Ehrhardt's Trade Mark book from c1976. See the images. It is Gold Filled 25 Year case.

Whenever you see the word WARRANTED is the give away for Gold Filled

Thanks guys...I guess it's hamburger tonight instead of steak.

I have a 2015 version of Roy Ehrhardt's book, but couldn't find this mark in it. Either way, it's a beautiful case.
Thanks again.
