   No problem with your english!  Appears to be an old 805, based on 
general shape, size, and the graphite anode.  These tubes are still 
being built but modern ones may have somewhat different anode shapes.  
It looked as if there might still be some traces of the label left.  One 
stunt which sometimes helps in reading a label which is hard or 
invisible to see is to place the tube in the refrigerator until it is 
cold and them remove it and breath on the portion where the label might 
be.  Sometimes the old printing will be visible as differences in the 
appearances of the condensation there.
