| To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} Copy to Wor.{Arthur Wormald - General Works Manager}E. re Lead Bronze Bearings for Bentley Cars. When we were talking about this previously and discussing the question of letting Paris have some for their Trials cars and for a few customers cars which Sr. Knows are driven hard, I had in mind that it was just a question of fitting lead bronze bearings instead of white metal, but it now transpires that additionally we require a larger gear oil pump, the design of which is not yet completed and I was going to say that probably we ought not to let Paris have these until they have been 10,000 miles tested, but. on looking at the list of points to be tested on 5-B-IV I see that Kelmet bearings are mixed up with narrow pin crankshaft and narrow pin light-ened drilled up connecting rods. The query, therefore, arises in my mind as to whether what we are going to test is something different from what we are proposing to let Paris have and whether the difference is of great importance. I also had in mind that, arising out of your recent suggestion that we ought to run some of these things on other cars, we might have put the lead bronze bearings on to the cars used by Bn.{W.O. Bentley / Mr Barrington} and Lp.{Mr Lappin} if it is not mixed up with the crankshaft and connecting rod important modification. Would you please let me know. Sg.{Arthur F. Sidgreaves - MD} | ||
