As far as I'm aware 'BN' is the Lucas code for components destined for Austin vehicles - Morris for example was 'A' possibly because they may have been their first major car manufacturing customer. I believe other car manufacturers using Lucas equipment were similarly given one or two letter codes. I can't remember the code for Wolseley though I do have a Wolseley engine so will check the Lucas dynamo, starter and distributor which should all carry the code.
