RARE 1985 / 1986 Honda CR50R CR50 CR60R CR60 Moto-Cross CYLINDER BARREL + HEAD

  
Here we have a very rare and hard to find cylinder barrel and cylinder head for a 1985 / 1986 50cc Honda CR50R child's moto-cross bike. There are no broken cooling fins on the barrel. There is one cooling fin broken on the head and the combustion chamber shows indent signs of broken rings (see pics). The cylinder comes with the inlet / reed valve and block assy. I'm sure these parts will also fit the 60cc CR60R engines as well?

Please enlarge the photos and have a good look at the item and condition for yourselves as they form part of my description. Any Q, s please ask.
