Looks like a scraper or shield of some sort to keep the small gritty stuff (and not so small) off of the brake pads.
I've never seen this on a Norton, so perhaps it was fabricated for purpose?

SERVICE RELEASE
N3/60
Front brake caliper incorporating stainless
steel disc scraper
All front disc brake Commando models
Worldwide (General Distribution)
motorcycles
The existing front brake caliper 061927 (serviced
as an assembly under part number 061926) has been
modified by the addition of two 2.55m.m diameter
holes on the rear face, to allow the incorporation
of a fully floating/self-aligning disc scraper
.part number 065143.
The scraper is designed to prevent dust and abrasive
particles entering the caliper yoke and initiating
abrasive wear of the disc and friction lining pads.
The new part numbers involved are as under:-
065173 Caliper assembly incorporating disc scraper
065143 Stainless steel disc scraper
NM25100 Screws (self-tapping)
Conversion'of existing calipers should be strictly
in accordance with the sketch. -DO NOT under any
circumstances drill the 2.55mm diameter holes
deeper than shown, otherwise the fully floating
facility will be completely lost. Additionally
-DO NOT overtighten the self-tap fixing screws for
the same reason.

you can see where its been scrapeing . :?
probably only a die hard puritan would refit it . Easier to hose out or blow out in there periodically .
The Disc Brake backing shields on cars , to keep the road grit from the discs , retain the road grit adjacent to the disc .
Lime Backroads and brakes arnt a good combination . Stuffing a hose in there ( WATER high pressure ) clears the trash out . Then theres the wheel bearings .
The waters not supposed to go in there .
Leave it in the sun after .
Then theres the going through a river then trying the late brakeing at the T intersection story . . .

LIkely only Westly and I even encounter much of what this scraper is advertised for but I can't think of a more arcane British bodge that seems would be more prone to grime and wearing and mud packing than if just left alone. Ugh at first glance I thought it a clever device to shield fork leaks fouling pads and disc.

Agreed, definitely a bodge. Sheet metal screws into an aluminum casting? Could be worse, I suppose. Could have used wood screws.
