Mark,
Agreed on all you say. Also as Tim says, the Readers Forum, Seen, Read and Heard, etc were all necessary reading. Bart's answers to any of our questions was factual and if he did not know the answer, he would say. This encouraged others to comment in later issues. In those day, pre-internet, this was the only real medium for collectors and enthusiast worldwide and through this I have got to know a lot of those people. The technical articles were second to none and often Bart would ask for information and details from official documents to back up his research on a forthcoming article, I recollect helping with info for a Morris Commercial article.
