The pressure cooker is a Fagor Elite, 6 liter. I own the 9.5 liter (10 quart) model. Identical bottom markings and the lid is the same.
The 6 liter Elite is marketed in the US as a “6 quart” whose capacity is actually 6.3 quarts = 6 liters.
They removed the pressure indicator valve and replaced it with a bolt to seal the cooker up tighter.
Looks close. I don’t have an actual model to compare.
In picture 1.
by hand: We can see where the side handle tore off. There appear to be two screw mounts. Definitely one on the lower side, cause the screw is still there. The top side has a strip of metal on the inside, but perhaps not screw.
Going down left in from that, we see a manufactured indent that matches the shape in the Elite Pressure Cooker Manual. There are two penetrations. One is just a hole, it is new the center of the oval indent. The other hole contains a screw and nut. This actually appears backwards from the elite picture.
A bit further down, there is a circular deep indent with large center hole. This feature does not sow on the Elite Pressure Cooker manual. What is this one for?
