the silver case is marked on the inside of the back cover 440 S 498 the "S" in between the Calibre and the Case number indicates it is Sterling Silver.
These were only made for a short while during 1941 when the sheet brass for the cases was commandeered by the US government for the War effort After the Japanese attacked Pearl Harbour, Gruen case makers, (Wadsworth) not wanting to lose the Gruen case contracts used Sterling Silver plate to make the cases until Brass was again available to them in 1942
So the Silver cases are quite rare only being made during 1941. Very rare item
