Fwiw.. the pressure cooker shown here is likely made in Europe. INOX is a french moniker for stainless steel from
acier inoxydable

The plate appears to be kind that's affixed to the bottom of the pot, not integrally layered into the pot, which probably suggests a cheaper version. Pressure cookers are not cheap, especially in stainless steel. A cheaper version might be found in departments stores, Marshalls, etc. More expensive ones only in specialty or online.
I think a European-made, value brand, or something made to mimic a European brand.
