UNIT TEST.

As you know we are fitting a Tecalemit type filter to the Bentley cars on production. This has been found necessary owing to the susceptibility to score of the tin aluminium alloy bearings. We consider, in view of this fact, it is worth while using Tecalemit filters on the test bed. This has been our practice in the Experimental Dept. for a considerable time.
