This is a rear left door lock assembly, rod, and knob off a 1965 Jaguar 3.8S.  It has held up well.  the knob has a little bit of a flat spot on the top, as shown in the last picture.  Looks more like a casting flaw to me, and you would have to go out of your way to notice.  The knob will also need a set screw.  But does look very presentable.  Turns as it should.  Overall this will be a great one to work with.  You cannot beat the original old parts. Get this for now or down the road. Sold with guarantee.  Shipping is gladly combined on multiple purchases.
