The date estimate for this one would be sometime around 1963. After Oct 1963 the engines had needle bearings for the gudgeon pin & should have steel cages for the bearings (but not always), the primer button was introduced at the same time, but these were available as a kit for fitting to older engines so aren't too helpful for the engine date. Keep the tank bracket if you remove it, also it could be useful to someone else it you don't want it, I can't quite make out the letter stamped into the other side of the crankcase, this would tell you which type of gearbox was originally fitted, the housing is one side of that gearbox.
