Have a look at this - first image on page.

Ray Newell's book Original Morris Minor shows very similar plug caps on a high-headlamp S/MM (page 31).

Srevice Parts book for the MM lists X32539 for the spark plug adaptor and that converts to a Champion number of A548, as shown in the pic below...

Looks like the original design was for a thumbscrew cap, a copper tubing crimp to the end of the ignition lead and a copper cored cable.

Palacebear is showing the Champion H.T.C. version. Not sure when they came in but not listed in my book.

Might be worth looking for press release images?

Just had a look in the BL Heritage book and it shows a pre-production MM with the same plug cap arrangement as I mentioned. I'm guessing that the car is shown in 1947 or early 1948?

Rob, those copper caps are just what I am after. Are you parting with them and if not where did you get them ?
