Here is the case top. The company name is vaultz. I believe they were cases that were not originally for rings so he took out the inside it came with and fit it with ring seats. These are the 2 rings- the Italian made DAK is gold and 800 silver hallmarked to I believe 14-fasces-MI in the lozenge. That maker is Enrico Locatelli of Milan. The ring has a neat elongated and center peaked cartouche. It is a tad over a size 10. Nice proper vent holes to allow the gas to escape when silver soldering the cartouche to the ring base. Next is a ring he found deeply blackened in patina at a local flea market near us. It is a propeller with a split band and I believe the French boar head hallmark upon the rear outer band. Inside is engraved with the word Frankreich - appearing to be misspelled as Frankreick but could be engraving error 1941. Is approximately 9.5 size.
