On conrods, the state of the little end eye and thread is vital. Many rods have been damaged by heavy dents from straightening jigs, and these often been applied wrong to curve rods in the middle. All should finally weigh similar. Some forgings certainly look superior to others.
The number on crank is the original engine number. Others presumably after market replacements, which may not be Austin.
The loose bearing is common. Remedy methods involving heating have shortened the life of very many shafts. Unexpected though it may be, the first cracks often appear at the last radius. No one seems to advocate but for those adept at precision lathe work it seems feasible to sleeve and to bore the housing for a (much less expensive) metric bearing. All crank radii must be maintained.
