Interesting that copy Best & Lloyd pumps were mentioned as I had exactly the same experience. The pump looked good and was reasonably well finished but did not work due to the lack of a one-way valve. I had the devil's own job convincing the seller that the pump did not work without a non-return ball bearing/spring in a fitting that wasn't there. The plunger went up and down moving the oil in the barrel but was unable to keep and transfer a fresh charge past the leather washer on the down-stroke. 6 emails later and the threat of a Paypal dispute eventually convinced him to accept a return and full refund.
