That's an Hermes Ambassador typewriter similar to the one shown here: https://www.flickr.com/photos/shordzi/6155039056/
These were top quality typewriters. The dedicated top "1.." keys were designed to ease typing numerical values in column.
They are described in Page 12 of the typewriter user's manual, chapter "Decimal tabulator" : http://munk.org/typecast/2011/09/30/hermes-ambassador-user-manual-late-50s-early-60s/
