As described, delivered quickly and works. Very nicely made and finished in the right materials. I'll know how good it really is in the next 50 years or so (which is how long the original lasted) but won't be around to write the then review. In the meantime I'm happy both with the quality and the price
The pump did not work when first fitted.
It had to be modified to make the arm sit on the cam properly and the valves had to be softened and manipulated to make them work.
