vintage stainless steel coffee pot, Mirro/Cory percolator w/extra filter disks

Old 1950s vintage, stainless steel vacuum brewing coffee pot. This coffee pot is a 6 cup size. The stainless coffee maker is marked "Mirro - Model 500", but the bakelite base/stand for the stainless steel upper pot is marked Cory. We're not sure if the stand is a later replacement piece with this pot or if maybe Cory was making parts for Mirro. The filter arrangement is a spring loaded metal filter disk, rather then the glass filter rod that is normally associated with the Cory vaculator coffee pots.

We're also including several additional Mirro metal coffee filter holding disks, still with the original box as shown in the photos. This coffee pot is in nice condition.
