I have a spare set of 1948 A7 long stroke crank cases for sale if anybody out there is interested. They are in reasonable condition with only a small piece of damage where one of the studs goes through at the rear in front of the gearbox and one of the primary cover bolt holes has a small piece missing though the bolt does thread in (see pics). Engine number YA7 41##. Looking for around £30 plus P&P. Can take to Stafford.
