Is the inside of Stainless faucet also stainless

faucet

I have this supposedly stainless faucet.

enter image description here

But when I peek inside. It doesn't look stainless, or maybe it's the rust sticking to the surface.

If a faucet is advertised as stainless. Is it stainless all the way (outside and inside)?

That is a difficult = expensive shape to make in stainless steel, so I doubt it is stainless. Solid chromium is never made as a product. The picture shows a gold color in the inside indicating a copper alloy. I suspect it is a German Silver ; a brass with 10 to 20 % nickel which makes it silver color ,no plating. These alloys are fine for water service. Do you have a problem ?
