For those interested in the Australian manufacture of 1800's and other BMC cars and trucks, the new BMC-Leyland Australia Heritage Group web site is now active at www.bmclaheritage.org.au. This Group comprises some hundreds of ex-employees and interested people whose mission is to essentially "keep the memories alive". Alas, the number of ex-employees still alive is steadily decreasing and a lot of original documents and photos have been donated to the Group and as a consequence. I am sure you will find this web site interesting. The similarity in style between it and the austineighteenhundred.com.au site is no accident.
One of the more interesting documents which has come to light is an explanation of the BMC part numbering system. A summary of the logic behind this can be found in an article by Peter Davis on both the above web sites. A comprehensive treatment of vehicle identification plates as fitted to Australian 1800's is now underway and explains what all those YJBBR and other codes mean.
