MG SHOP TOOLS - Factory Original Issue
Also see MG Garage Tools Tech
And MG Traveling Tools, factory issue

This is a list of factory issue special workshop tools to be used on the MGA. Many of these were produced by Churchill on order from MG or BMC (or Austin earlier), in which case the Churchill part number is the same as the BMC part number. Illustrations of many of these tools can be found in Section Q of the MGA Workshop Manual. I will post links and web pages here when photos are available. If you have any pictures of these special factory tools, all contributions would be appreciated.

Dealers were supplied factory tools made by Churchill of England until the early 1970's. Then began using tools made in the USA by Zelinda, which are identical, Rear hub nut spanner, Zelinda same quality and part number, but have 2 small impressed dots (one is red) to identify. Zelinda was started by a German Engineer who had designed some of the tools, and had original drawings and production rights outside England, but appreciate more exact details. I now have an example of a Zelinda tool, shown at bottom of page 18G152.htm.

If you would like to procure any of these original tools, check with the eBay store for Old English Motor Company, and search for the part number of the desired tool. If it does not show up immediately, send a request to the store owner, as he may have it.
