The rubber bottom is worn out as shown. Became dry from many years of storage. When I used the unit I simply sat it on the rubber piece and it worked fine that way but you may want to replace the rubber or at least glue it on. There is some rust around the bottom edge as you can see and also a small amount in the area that catches runoff espresso. I have not attempted to remove the rust but I believe this could be restored beautifully with a little effort.
In the meantime, it is perfectly useable as is. It does have a USA plug and power. Appears to be a 1975 model.
