I modified an E3L with a band type end cover to accept the later alloy one piece part, but it involves filing the small alloy locating boss on the dynamo body flush,.............

  I know you don't need to, but for others doing same, rather than file off the boss which would make it hard to locate a band if need be for future use, I decided to carve a recess in the cover with the Dremel

........and modifying or replacing the tufnol brush plate with the later type which has the internal female wire connections.  Also there is no provision for the o ring which should seal the one piece cover, and you need the rubber cable entry grommet.

 My body has provision for an 'O' ring, but not "the tufnol brush plate with the later type which has the internal female wire connections" , so I had an issue a year or so ago where the wires rubbed on the inside of the cover and caused a short which blew a couple of batteries  (only- luckily) before I figured it out; rectified this by cutting the bottom off a perfect size plastic drink bottle and jamming it in- works so far

This is a really timely question for me. For want of two cents worth of locktite I lost my chromed end cover, the type described by Ivor, having the screw recess in the bump-out. It turns out these covers are not in great supply as they are not common on eBay and are either out of stock at stockists or really pricey. Anyone care to suggest a reasonable source?

Terry,

Thank you, kindly. Very interesting regarding the polishing. Andy mentioned he had them and I intend to contact him.

The original end caps were steel, later were aluminium.
The repro caps available seem to be mostly steel.
I have bought some and they were variable in quality. Some dented and needed beating out and repainting.
All were rusting through the paint on the inside so needed cleaning and repainting.

The E3H was too short to fit on the A10 plunger, so I'm putting an E3L together with this brush mount. Will a one piece cover fit this ? It looks to me that the F & D bullets push straight into this plate. It was an armature with a gear on the end but I machined a taper for the sprocket.

The E3H was used until 1949.
That is the end for the one piece cover. There is a retaining plate for the wires.
