Brake Drum Inspection Hole Blank

[Drewmotty]

Does anyone have a part number or source for the metal blank which fits in the inspection hole on the brake drums. 
The parts books don’t show a hole in the drum or the blank.

The drum fitted to the Girling 10” rear brakes I would say is a carry over from the 10” Lockheed drum fitment on TR 2/3 that had a snail cam type brake shoe adjuster (s).  Not sure of the size of the hole this fits but we used to sell 2A7228 rubber brake drum hole plugs to TR owners et al   -  also used on the Healey with Girling brakes.

I know what you mean by the metal plug but cannot point you at a source.  The Morris Minor equiv metal plug for round hole was ACA5102 but is dead and gone.

rubber plug.

Why bother, it's covered up when the wheel is in situ anyway (possible not true for wire wheels ?)

By the way the 9" "Girling" drums have the hole also.

The rubber plug that Peter refers to 2A7228 is also fitted on the drum brakes of Midgets and Sprites as well as M Minors, link - Moss item 2A7228

It is not listed for the TR drums, neither is any blank or plug shown on the brake drum diagrams on the Moss site. On our Midget the steel wheels have a hole where these bungs, which sit proud from the drum when fitted, poke through. The TR steel wheels don't have a similar hole so these bungs wouldn't be suitable.
