This page and document is not part of any Service Parts List for MGA, but this seemed like a convenient place to drop it into the web site (for now). It is a hand penciled document for factory internal use defining what ranges of AJD- part numbers would be used for what type of hardware parts. This logically dates to a time shortly after the merger of Austin and Morris to form BMC (perhaps 1952). It lays out the numbering scheme to combine and consolidate Austin and Morris part numbers into a single standard number set. You can click on the image below to download a larger PDF image.
You can (if you like) compare the AJD numbers on the previous page to see how they may fit into this numbering scheme. It might be interesting to some day accumulate the extended list of several thousand parts that could fit into this AJD- number format (but not me, and not today). But if you have an AJD part or part number that you cannot identify, this list may give you a rough idea of what it might be.
